Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102942, here are decompositions:

  • 11 + 102931 = 102942
  • 13 + 102929 = 102942
  • 29 + 102913 = 102942
  • 31 + 102911 = 102942
  • 61 + 102881 = 102942
  • 71 + 102871 = 102942
  • 83 + 102859 = 102942
  • 101 + 102841 = 102942

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 102,942 and was likely granted around 1870.

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