Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509566, here are decompositions:

  • 3 + 509563 = 509566
  • 17 + 509549 = 509566
  • 23 + 509543 = 509566
  • 53 + 509513 = 509566
  • 89 + 509477 = 509566
  • 137 + 509429 = 509566
  • 149 + 509417 = 509566
  • 173 + 509393 = 509566

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 509,566 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 509566 first appears in π at position 247,458 of the decimal expansion (the 247,458ordinal-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.
