Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617210, here are decompositions:

  • 3 + 8617207 = 8617210
  • 23 + 8617187 = 8617210
  • 101 + 8617109 = 8617210
  • 113 + 8617097 = 8617210
  • 137 + 8617073 = 8617210
  • 263 + 8616947 = 8617210
  • 293 + 8616917 = 8617210
  • 383 + 8616827 = 8617210

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 8,617,210 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 8617210 first appears in π at position 886,241 of the decimal expansion (the 886,241ordinal-suffix:st 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.
