Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 124172, here are decompositions:

  • 19 + 124153 = 124172
  • 151 + 124021 = 124172
  • 193 + 123979 = 124172
  • 199 + 123973 = 124172
  • 241 + 123931 = 124172
  • 439 + 123733 = 124172
  • 541 + 123631 = 124172
  • 571 + 123601 = 124172

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 124,172 and was likely granted around 1871.

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