Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649836, here are decompositions:

  • 43 + 8649793 = 8649836
  • 73 + 8649763 = 8649836
  • 79 + 8649757 = 8649836
  • 199 + 8649637 = 8649836
  • 367 + 8649469 = 8649836
  • 373 + 8649463 = 8649836
  • 487 + 8649349 = 8649836
  • 733 + 8649103 = 8649836

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 8,649,836 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 8649836 first appears in π at position 880,716 of the decimal expansion (the 880,716ordinal-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.
