Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 143844, here are decompositions:

  • 11 + 143833 = 143844
  • 13 + 143831 = 143844
  • 17 + 143827 = 143844
  • 23 + 143821 = 143844
  • 31 + 143813 = 143844
  • 37 + 143807 = 143844
  • 47 + 143797 = 143844
  • 53 + 143791 = 143844

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 143,844 and was likely granted around 1873.

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