Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 186984, here are decompositions:

  • 37 + 186947 = 186984
  • 67 + 186917 = 186984
  • 101 + 186883 = 186984
  • 107 + 186877 = 186984
  • 113 + 186871 = 186984
  • 191 + 186793 = 186984
  • 211 + 186773 = 186984
  • 223 + 186761 = 186984

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 186,984 and was likely granted around 1875.

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