Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726870, here are decompositions:

  • 7 + 8726863 = 8726870
  • 67 + 8726803 = 8726870
  • 109 + 8726761 = 8726870
  • 157 + 8726713 = 8726870
  • 193 + 8726677 = 8726870
  • 199 + 8726671 = 8726870
  • 223 + 8726647 = 8726870
  • 283 + 8726587 = 8726870

Showing the first eight; more decompositions exist.

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 8,726,870 and was likely granted around 2014.

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

Position in π

The digit sequence 8726870 first appears in π at position 629,195 of the decimal expansion (the 629,195ordinal-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.
