Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 144936, here are decompositions:

  • 5 + 144931 = 144936
  • 19 + 144917 = 144936
  • 37 + 144899 = 144936
  • 47 + 144889 = 144936
  • 53 + 144883 = 144936
  • 89 + 144847 = 144936
  • 97 + 144839 = 144936
  • 107 + 144829 = 144936

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 144,936 and was likely granted around 1873.

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