Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011812, here are decompositions:

  • 13 + 1011799 = 1011812
  • 79 + 1011733 = 1011812
  • 163 + 1011649 = 1011812
  • 181 + 1011631 = 1011812
  • 211 + 1011601 = 1011812
  • 223 + 1011589 = 1011812
  • 229 + 1011583 = 1011812
  • 421 + 1011391 = 1011812

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 1812 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 1812-10-01 (MMDYYYY (US, single-digit day))
  • 1812-01-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,011,812 and was likely granted around 1911.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1011812 first appears in π at position 980,956 of the decimal expansion (the 980,956ordinal-suffix:th digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
