Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105984, here are decompositions:

  • 7 + 105977 = 105984
  • 13 + 105971 = 105984
  • 17 + 105967 = 105984
  • 31 + 105953 = 105984
  • 41 + 105943 = 105984
  • 71 + 105913 = 105984
  • 101 + 105883 = 105984
  • 113 + 105871 = 105984

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 105,984 and was likely granted around 1870.

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