Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148940, here are decompositions:

  • 7 + 148933 = 148940
  • 13 + 148927 = 148940
  • 19 + 148921 = 148940
  • 67 + 148873 = 148940
  • 73 + 148867 = 148940
  • 79 + 148861 = 148940
  • 157 + 148783 = 148940
  • 193 + 148747 = 148940

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 148,940 and was likely granted around 1873.

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