Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8654820, here are decompositions:

  • 11 + 8654809 = 8654820
  • 17 + 8654803 = 8654820
  • 47 + 8654773 = 8654820
  • 59 + 8654761 = 8654820
  • 61 + 8654759 = 8654820
  • 67 + 8654753 = 8654820
  • 71 + 8654749 = 8654820
  • 107 + 8654713 = 8654820

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 8,654,820 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 8654820 first appears in π at position 829,587 of the decimal expansion (the 829,587ordinal-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.
