Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 495580, here are decompositions:

  • 11 + 495569 = 495580
  • 17 + 495563 = 495580
  • 23 + 495557 = 495580
  • 53 + 495527 = 495580
  • 89 + 495491 = 495580
  • 131 + 495449 = 495580
  • 167 + 495413 = 495580
  • 179 + 495401 = 495580

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 495,580 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 495580 first appears in π at position 435,002 of the decimal expansion (the 435,002ordinal-suffix:nd 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.
