Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8617278, here are decompositions:

  • 17 + 8617261 = 8617278
  • 41 + 8617237 = 8617278
  • 67 + 8617211 = 8617278
  • 71 + 8617207 = 8617278
  • 101 + 8617177 = 8617278
  • 107 + 8617171 = 8617278
  • 149 + 8617129 = 8617278
  • 181 + 8617097 = 8617278

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 8,617,278 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 8617278 first appears in π at position 1,132 of the decimal expansion (the 1,132ordinal-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.
