Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102884, here are decompositions:

  • 3 + 102881 = 102884
  • 7 + 102877 = 102884
  • 13 + 102871 = 102884
  • 43 + 102841 = 102884
  • 73 + 102811 = 102884
  • 211 + 102673 = 102884
  • 241 + 102643 = 102884
  • 277 + 102607 = 102884

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 102,884 and was likely granted around 1870.

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