Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 542730, here are decompositions:

  • 7 + 542723 = 542730
  • 11 + 542719 = 542730
  • 17 + 542713 = 542730
  • 37 + 542693 = 542730
  • 43 + 542687 = 542730
  • 47 + 542683 = 542730
  • 127 + 542603 = 542730
  • 131 + 542599 = 542730

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 542,730 and was likely granted around 1895.

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