Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491610, here are decompositions:

  • 17 + 491593 = 491610
  • 19 + 491591 = 491610
  • 29 + 491581 = 491610
  • 71 + 491539 = 491610
  • 73 + 491537 = 491610
  • 79 + 491531 = 491610
  • 83 + 491527 = 491610
  • 107 + 491503 = 491610

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 491,610 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 491610 first appears in π at position 493,266 of the decimal expansion (the 493,266ordinal-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.
