Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625830, here are decompositions:

  • 19 + 8625811 = 8625830
  • 43 + 8625787 = 8625830
  • 97 + 8625733 = 8625830
  • 181 + 8625649 = 8625830
  • 193 + 8625637 = 8625830
  • 271 + 8625559 = 8625830
  • 277 + 8625553 = 8625830
  • 313 + 8625517 = 8625830

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 8,625,830 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 8625830 first appears in π at position 913,589 of the decimal expansion (the 913,589ordinal-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.
