Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 516840, here are decompositions:

  • 11 + 516829 = 516840
  • 19 + 516821 = 516840
  • 29 + 516811 = 516840
  • 47 + 516793 = 516840
  • 83 + 516757 = 516840
  • 113 + 516727 = 516840
  • 127 + 516713 = 516840
  • 131 + 516709 = 516840

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 516,840 and was likely granted around 1894.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 516840 first appears in π at position 92,676 of the decimal expansion (the 92,676ordinal-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.
