Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146970, here are decompositions:

  • 17 + 146953 = 146970
  • 29 + 146941 = 146970
  • 37 + 146933 = 146970
  • 53 + 146917 = 146970
  • 79 + 146891 = 146970
  • 113 + 146857 = 146970
  • 127 + 146843 = 146970
  • 137 + 146833 = 146970

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 146,970 and was likely granted around 1873.

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