Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618422, here are decompositions:

  • 83 + 8618339 = 8618422
  • 149 + 8618273 = 8618422
  • 179 + 8618243 = 8618422
  • 359 + 8618063 = 8618422
  • 389 + 8618033 = 8618422
  • 401 + 8618021 = 8618422
  • 431 + 8617991 = 8618422
  • 479 + 8617943 = 8618422

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 8,618,422 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 8618422 first appears in π at position 205,637 of the decimal expansion (the 205,637ordinal-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.
