Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634686, here are decompositions:

  • 7 + 8634679 = 8634686
  • 19 + 8634667 = 8634686
  • 433 + 8634253 = 8634686
  • 523 + 8634163 = 8634686
  • 547 + 8634139 = 8634686
  • 727 + 8633959 = 8634686
  • 787 + 8633899 = 8634686
  • 829 + 8633857 = 8634686

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 8,634,686 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 8634686 first appears in π at position 195,834 of the decimal expansion (the 195,834ordinal-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.
