Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186942, here are decompositions:

  • 53 + 186889 = 186942
  • 59 + 186883 = 186942
  • 71 + 186871 = 186942
  • 73 + 186869 = 186942
  • 83 + 186859 = 186942
  • 101 + 186841 = 186942
  • 149 + 186793 = 186942
  • 179 + 186763 = 186942

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 186,942 and was likely granted around 1875.

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