Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1011218, here are decompositions:

  • 79 + 1011139 = 1011218
  • 127 + 1011091 = 1011218
  • 139 + 1011079 = 1011218
  • 151 + 1011067 = 1011218
  • 181 + 1011037 = 1011218
  • 337 + 1010881 = 1011218
  • 409 + 1010809 = 1011218
  • 421 + 1010797 = 1011218

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Monday, January 1, 1218 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 1218-10-01 (MMDYYYY (US, single-digit day))
  • 1218-01-10 (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 1,011,218 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 1011218 first appears in π at position 946,807 of the decimal expansion (the 946,807ordinal-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.
