Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8642610, here are decompositions:

  • 19 + 8642591 = 8642610
  • 29 + 8642581 = 8642610
  • 43 + 8642567 = 8642610
  • 101 + 8642509 = 8642610
  • 103 + 8642507 = 8642610
  • 157 + 8642453 = 8642610
  • 181 + 8642429 = 8642610
  • 227 + 8642383 = 8642610

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 8,642,610 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 8642610 first appears in π at position 777,399 of the decimal expansion (the 777,399ordinal-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.
