Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162130, here are decompositions:

  • 11 + 162119 = 162130
  • 71 + 162059 = 162130
  • 113 + 162017 = 162130
  • 131 + 161999 = 162130
  • 173 + 161957 = 162130
  • 251 + 161879 = 162130
  • 257 + 161873 = 162130
  • 347 + 161783 = 162130

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 162,130 and was likely granted around 1874.

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