Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8709130, here are decompositions:

  • 71 + 8709059 = 8709130
  • 167 + 8708963 = 8709130
  • 281 + 8708849 = 8709130
  • 389 + 8708741 = 8709130
  • 467 + 8708663 = 8709130
  • 491 + 8708639 = 8709130
  • 503 + 8708627 = 8709130
  • 509 + 8708621 = 8709130

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 8,709,130 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 8709130 first appears in π at position 496,510 of the decimal expansion (the 496,510ordinal-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.
