Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 142452, here are decompositions:

  • 19 + 142433 = 142452
  • 31 + 142421 = 142452
  • 61 + 142391 = 142452
  • 71 + 142381 = 142452
  • 83 + 142369 = 142452
  • 181 + 142271 = 142452
  • 229 + 142223 = 142452
  • 241 + 142211 = 142452

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 142,452 and was likely granted around 1872.

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