Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148790, here are decompositions:

  • 7 + 148783 = 148790
  • 43 + 148747 = 148790
  • 67 + 148723 = 148790
  • 79 + 148711 = 148790
  • 97 + 148693 = 148790
  • 127 + 148663 = 148790
  • 151 + 148639 = 148790
  • 157 + 148633 = 148790

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 148,790 and was likely granted around 1873.

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