Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8656290, here are decompositions:

  • 7 + 8656283 = 8656290
  • 11 + 8656279 = 8656290
  • 17 + 8656273 = 8656290
  • 37 + 8656253 = 8656290
  • 59 + 8656231 = 8656290
  • 101 + 8656189 = 8656290
  • 113 + 8656177 = 8656290
  • 127 + 8656163 = 8656290

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 8,656,290 and was likely granted around 2014.

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

Position in π

The digit sequence 8656290 first appears in π at position 594,928 of the decimal expansion (the 594,928ordinal-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.
