Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509940, here are decompositions:

  • 19 + 509921 = 509940
  • 29 + 509911 = 509940
  • 31 + 509909 = 509940
  • 61 + 509879 = 509940
  • 73 + 509867 = 509940
  • 97 + 509843 = 509940
  • 103 + 509837 = 509940
  • 107 + 509833 = 509940

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 509,940 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 509940 first appears in π at position 914,734 of the decimal expansion (the 914,734ordinal-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.
