Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620188, here are decompositions:

  • 29 + 8620159 = 8620188
  • 37 + 8620151 = 8620188
  • 47 + 8620141 = 8620188
  • 67 + 8620121 = 8620188
  • 79 + 8620109 = 8620188
  • 139 + 8620049 = 8620188
  • 191 + 8619997 = 8620188
  • 251 + 8619937 = 8620188

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 8,620,188 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 8620188 first appears in π at position 540,606 of the decimal expansion (the 540,606ordinal-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.
