Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103040, here are decompositions:

  • 73 + 102967 = 103040
  • 109 + 102931 = 103040
  • 127 + 102913 = 103040
  • 163 + 102877 = 103040
  • 181 + 102859 = 103040
  • 199 + 102841 = 103040
  • 211 + 102829 = 103040
  • 229 + 102811 = 103040

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 103,040 and was likely granted around 1870.

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