Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513086, here are decompositions:

  • 3 + 513083 = 513086
  • 19 + 513067 = 513086
  • 73 + 513013 = 513086
  • 97 + 512989 = 513086
  • 109 + 512977 = 513086
  • 127 + 512959 = 513086
  • 157 + 512929 = 513086
  • 283 + 512803 = 513086

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 513,086 and was likely granted around 1893.

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

Position in π

The digit sequence 513086 first appears in π at position 88,475 of the decimal expansion (the 88,475ordinal-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.
