Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648816, here are decompositions:

  • 3 + 8648813 = 8648816
  • 19 + 8648797 = 8648816
  • 37 + 8648779 = 8648816
  • 67 + 8648749 = 8648816
  • 79 + 8648737 = 8648816
  • 139 + 8648677 = 8648816
  • 283 + 8648533 = 8648816
  • 499 + 8648317 = 8648816

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 8,648,816 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 8648816 first appears in π at position 39,437 of the decimal expansion (the 39,437ordinal-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.
