Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101238, here are decompositions:

  • 17 + 101221 = 101238
  • 29 + 101209 = 101238
  • 31 + 101207 = 101238
  • 41 + 101197 = 101238
  • 79 + 101159 = 101238
  • 89 + 101149 = 101238
  • 97 + 101141 = 101238
  • 127 + 101111 = 101238

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 101,238 and was likely granted around 1870.

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