Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509582, here are decompositions:

  • 13 + 509569 = 509582
  • 19 + 509563 = 509582
  • 61 + 509521 = 509582
  • 193 + 509389 = 509582
  • 223 + 509359 = 509582
  • 379 + 509203 = 509582
  • 433 + 509149 = 509582
  • 613 + 508969 = 509582

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 509,582 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 509582 first appears in π at position 143,461 of the decimal expansion (the 143,461ordinal-suffix:st 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.
