Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8697828, here are decompositions:

  • 5 + 8697823 = 8697828
  • 17 + 8697811 = 8697828
  • 19 + 8697809 = 8697828
  • 31 + 8697797 = 8697828
  • 37 + 8697791 = 8697828
  • 59 + 8697769 = 8697828
  • 131 + 8697697 = 8697828
  • 137 + 8697691 = 8697828

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 8,697,828 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 8697828 first appears in π at position 513,876 of the decimal expansion (the 513,876ordinal-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.
