Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 148900, here are decompositions:

  • 41 + 148859 = 148900
  • 47 + 148853 = 148900
  • 71 + 148829 = 148900
  • 83 + 148817 = 148900
  • 107 + 148793 = 148900
  • 137 + 148763 = 148900
  • 173 + 148727 = 148900
  • 179 + 148721 = 148900

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 148,900 and was likely granted around 1873.

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