Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180152, here are decompositions:

  • 79 + 180073 = 180152
  • 109 + 180043 = 180152
  • 151 + 180001 = 180152
  • 163 + 179989 = 180152
  • 199 + 179953 = 180152
  • 229 + 179923 = 180152
  • 331 + 179821 = 180152
  • 373 + 179779 = 180152

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 180,152 and was likely granted around 1875.

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