Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542118, here are decompositions:

  • 7 + 542111 = 542118
  • 37 + 542081 = 542118
  • 47 + 542071 = 542118
  • 97 + 542021 = 542118
  • 127 + 541991 = 542118
  • 131 + 541987 = 542118
  • 151 + 541967 = 542118
  • 167 + 541951 = 542118

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 542,118 and was likely granted around 1895.

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