Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 128056, here are decompositions:

  • 3 + 128053 = 128056
  • 23 + 128033 = 128056
  • 59 + 127997 = 128056
  • 83 + 127973 = 128056
  • 179 + 127877 = 128056
  • 197 + 127859 = 128056
  • 239 + 127817 = 128056
  • 293 + 127763 = 128056

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 128,056 and was likely granted around 1872.

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