Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620474, here are decompositions:

  • 113 + 8620361 = 8620474
  • 167 + 8620307 = 8620474
  • 197 + 8620277 = 8620474
  • 257 + 8620217 = 8620474
  • 263 + 8620211 = 8620474
  • 353 + 8620121 = 8620474
  • 431 + 8620043 = 8620474
  • 617 + 8619857 = 8620474

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 8,620,474 and was likely granted around 2013.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 8620474 first appears in π at position 712,252 of the decimal expansion (the 712,252ordinal-suffix:nd 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.
