Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672940, here are decompositions:

  • 7 + 8672933 = 8672940
  • 13 + 8672927 = 8672940
  • 43 + 8672897 = 8672940
  • 71 + 8672869 = 8672940
  • 79 + 8672861 = 8672940
  • 109 + 8672831 = 8672940
  • 139 + 8672801 = 8672940
  • 149 + 8672791 = 8672940

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 8,672,940 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 8672940 first appears in π at position 484,651 of the decimal expansion (the 484,651ordinal-suffix:st 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.
