Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629646, here are decompositions:

  • 139 + 8629507 = 8629646
  • 163 + 8629483 = 8629646
  • 199 + 8629447 = 8629646
  • 313 + 8629333 = 8629646
  • 349 + 8629297 = 8629646
  • 367 + 8629279 = 8629646
  • 433 + 8629213 = 8629646
  • 523 + 8629123 = 8629646

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 8,629,646 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 8629646 first appears in π at position 366,838 of the decimal expansion (the 366,838ordinal-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.
