Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 108980, here are decompositions:

  • 13 + 108967 = 108980
  • 19 + 108961 = 108980
  • 31 + 108949 = 108980
  • 37 + 108943 = 108980
  • 73 + 108907 = 108980
  • 97 + 108883 = 108980
  • 103 + 108877 = 108980
  • 181 + 108799 = 108980

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 108,980 and was likely granted around 1871.

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