Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718812, here are decompositions:

  • 13 + 8718799 = 8718812
  • 19 + 8718793 = 8718812
  • 79 + 8718733 = 8718812
  • 103 + 8718709 = 8718812
  • 139 + 8718673 = 8718812
  • 163 + 8718649 = 8718812
  • 211 + 8718601 = 8718812
  • 241 + 8718571 = 8718812

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 8,718,812 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 8718812 first appears in π at position 339,564 of the decimal expansion (the 339,564ordinal-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.
