Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8739380, here are decompositions:

  • 31 + 8739349 = 8739380
  • 43 + 8739337 = 8739380
  • 193 + 8739187 = 8739380
  • 211 + 8739169 = 8739380
  • 283 + 8739097 = 8739380
  • 373 + 8739007 = 8739380
  • 379 + 8739001 = 8739380
  • 499 + 8738881 = 8739380

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 8,739,380 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 8739380 first appears in π at position 688,154 of the decimal expansion (the 688,154ordinal-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.
