Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015986, here are decompositions:

  • 5 + 1015981 = 1015986
  • 19 + 1015967 = 1015986
  • 67 + 1015919 = 1015986
  • 73 + 1015913 = 1015986
  • 79 + 1015907 = 1015986
  • 89 + 1015897 = 1015986
  • 109 + 1015877 = 1015986
  • 157 + 1015829 = 1015986

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Wednesday, January 1, 5986 (MDDYYYY (US, single-digit month)).

Other possible interpretations (2)
  • 5986-10-01 (MMDYYYY (US, single-digit day))
  • 5986-01-10 (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 1,015,986 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 1015986 first appears in π at position 337,457 of the decimal expansion (the 337,457ordinal-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.
