Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542122, here are decompositions:

  • 3 + 542119 = 542122
  • 5 + 542117 = 542122
  • 11 + 542111 = 542122
  • 29 + 542093 = 542122
  • 41 + 542081 = 542122
  • 59 + 542063 = 542122
  • 101 + 542021 = 542122
  • 131 + 541991 = 542122

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 542,122 and was likely granted around 1895.

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