Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8674978, here are decompositions:

  • 17 + 8674961 = 8674978
  • 41 + 8674937 = 8674978
  • 89 + 8674889 = 8674978
  • 197 + 8674781 = 8674978
  • 251 + 8674727 = 8674978
  • 311 + 8674667 = 8674978
  • 359 + 8674619 = 8674978
  • 401 + 8674577 = 8674978

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 8,674,978 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 8674978 first appears in π at position 263,732 of the decimal expansion (the 263,732ordinal-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.
