Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143656, here are decompositions:

  • 3 + 143653 = 143656
  • 5 + 143651 = 143656
  • 47 + 143609 = 143656
  • 83 + 143573 = 143656
  • 89 + 143567 = 143656
  • 137 + 143519 = 143656
  • 167 + 143489 = 143656
  • 173 + 143483 = 143656

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 143,656 and was likely granted around 1873.

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