Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678830, here are decompositions:

  • 47 + 8678783 = 8678830
  • 53 + 8678777 = 8678830
  • 71 + 8678759 = 8678830
  • 89 + 8678741 = 8678830
  • 131 + 8678699 = 8678830
  • 137 + 8678693 = 8678830
  • 191 + 8678639 = 8678830
  • 227 + 8678603 = 8678830

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 8,678,830 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 8678830 first appears in π at position 630,304 of the decimal expansion (the 630,304ordinal-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.
