Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749636, here are decompositions:

  • 23 + 8749613 = 8749636
  • 29 + 8749607 = 8749636
  • 47 + 8749589 = 8749636
  • 167 + 8749469 = 8749636
  • 179 + 8749457 = 8749636
  • 197 + 8749439 = 8749636
  • 293 + 8749343 = 8749636
  • 503 + 8749133 = 8749636

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 8,749,636 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 8749636 first appears in π at position 529,207 of the decimal expansion (the 529,207ordinal-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.
