Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509904, here are decompositions:

  • 37 + 509867 = 509904
  • 41 + 509863 = 509904
  • 61 + 509843 = 509904
  • 67 + 509837 = 509904
  • 71 + 509833 = 509904
  • 103 + 509801 = 509904
  • 107 + 509797 = 509904
  • 137 + 509767 = 509904

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 509,904 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 509904 first appears in π at position 162,388 of the decimal expansion (the 162,388ordinal-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.
