Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 490660, here are decompositions:

  • 17 + 490643 = 490660
  • 29 + 490631 = 490660
  • 41 + 490619 = 490660
  • 83 + 490577 = 490660
  • 89 + 490571 = 490660
  • 101 + 490559 = 490660
  • 167 + 490493 = 490660
  • 179 + 490481 = 490660

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 490,660 and was likely granted around 1892.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 490660 first appears in π at position 994,114 of the decimal expansion (the 994,114ordinal-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.
