Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611380, here are decompositions:

  • 23 + 8611357 = 8611380
  • 31 + 8611349 = 8611380
  • 59 + 8611321 = 8611380
  • 73 + 8611307 = 8611380
  • 79 + 8611301 = 8611380
  • 83 + 8611297 = 8611380
  • 97 + 8611283 = 8611380
  • 131 + 8611249 = 8611380

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 8,611,380 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 8611380 first appears in π at position 708,372 of the decimal expansion (the 708,372ordinal-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.
