Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688180, here are decompositions:

  • 13 + 8688167 = 8688180
  • 19 + 8688161 = 8688180
  • 23 + 8688157 = 8688180
  • 37 + 8688143 = 8688180
  • 47 + 8688133 = 8688180
  • 71 + 8688109 = 8688180
  • 79 + 8688101 = 8688180
  • 97 + 8688083 = 8688180

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 8,688,180 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 8688180 first appears in π at position 113,137 of the decimal expansion (the 113,137ordinal-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.
