Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618474, here are decompositions:

  • 31 + 8618443 = 8618474
  • 61 + 8618413 = 8618474
  • 97 + 8618377 = 8618474
  • 157 + 8618317 = 8618474
  • 181 + 8618293 = 8618474
  • 223 + 8618251 = 8618474
  • 367 + 8618107 = 8618474
  • 433 + 8618041 = 8618474

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 8,618,474 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 8618474 first appears in π at position 644,092 of the decimal expansion (the 644,092ordinal-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.
