Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627686, here are decompositions:

  • 5 + 8627681 = 8627686
  • 47 + 8627639 = 8627686
  • 59 + 8627627 = 8627686
  • 83 + 8627603 = 8627686
  • 113 + 8627573 = 8627686
  • 173 + 8627513 = 8627686
  • 239 + 8627447 = 8627686
  • 257 + 8627429 = 8627686

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 8,627,686 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 8627686 first appears in π at position 133,787 of the decimal expansion (the 133,787ordinal-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.
