Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509660, here are decompositions:

  • 7 + 509653 = 509660
  • 13 + 509647 = 509660
  • 37 + 509623 = 509660
  • 79 + 509581 = 509660
  • 97 + 509563 = 509660
  • 103 + 509557 = 509660
  • 139 + 509521 = 509660
  • 211 + 509449 = 509660

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 509,660 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 509660 first appears in π at position 427,285 of the decimal expansion (the 427,285ordinal-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.
