Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155174, here are decompositions:

  • 3 + 155171 = 155174
  • 7 + 155167 = 155174
  • 13 + 155161 = 155174
  • 37 + 155137 = 155174
  • 127 + 155047 = 155174
  • 157 + 155017 = 155174
  • 193 + 154981 = 155174
  • 241 + 154933 = 155174

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 155,174 and was likely granted around 1873.

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