Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 491712, here are decompositions:

  • 5 + 491707 = 491712
  • 43 + 491669 = 491712
  • 59 + 491653 = 491712
  • 61 + 491651 = 491712
  • 73 + 491639 = 491712
  • 79 + 491633 = 491712
  • 101 + 491611 = 491712
  • 131 + 491581 = 491712

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 491,712 and was likely granted around 1893.

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