Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8611904, here are decompositions:

  • 13 + 8611891 = 8611904
  • 31 + 8611873 = 8611904
  • 181 + 8611723 = 8611904
  • 241 + 8611663 = 8611904
  • 271 + 8611633 = 8611904
  • 307 + 8611597 = 8611904
  • 331 + 8611573 = 8611904
  • 373 + 8611531 = 8611904

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 8,611,904 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 8611904 first appears in π at position 585,168 of the decimal expansion (the 585,168ordinal-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.
