Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667178, here are decompositions:

  • 11 + 8667167 = 8667178
  • 41 + 8667137 = 8667178
  • 239 + 8666939 = 8667178
  • 251 + 8666927 = 8667178
  • 431 + 8666747 = 8667178
  • 467 + 8666711 = 8667178
  • 587 + 8666591 = 8667178
  • 659 + 8666519 = 8667178

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 8,667,178 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 8667178 first appears in π at position 67,525 of the decimal expansion (the 67,525ordinal-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.
