Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 178148, here are decompositions:

  • 7 + 178141 = 178148
  • 31 + 178117 = 178148
  • 79 + 178069 = 178148
  • 109 + 178039 = 178148
  • 127 + 178021 = 178148
  • 181 + 177967 = 178148
  • 199 + 177949 = 178148
  • 241 + 177907 = 178148

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 178,148 and was likely granted around 1874.

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