Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8677220, here are decompositions:

  • 163 + 8677057 = 8677220
  • 193 + 8677027 = 8677220
  • 229 + 8676991 = 8677220
  • 271 + 8676949 = 8677220
  • 283 + 8676937 = 8677220
  • 337 + 8676883 = 8677220
  • 373 + 8676847 = 8677220
  • 421 + 8676799 = 8677220

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 8,677,220 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 8677220 first appears in π at position 342,832 of the decimal expansion (the 342,832ordinal-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.
