Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 509490, here are decompositions:

  • 13 + 509477 = 509490
  • 41 + 509449 = 509490
  • 61 + 509429 = 509490
  • 73 + 509417 = 509490
  • 97 + 509393 = 509490
  • 101 + 509389 = 509490
  • 127 + 509363 = 509490
  • 131 + 509359 = 509490

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 509,490 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 509490 first appears in π at position 800,617 of the decimal expansion (the 800,617ordinal-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.
