Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152742, here are decompositions:

  • 13 + 152729 = 152742
  • 19 + 152723 = 152742
  • 61 + 152681 = 152742
  • 71 + 152671 = 152742
  • 101 + 152641 = 152742
  • 103 + 152639 = 152742
  • 113 + 152629 = 152742
  • 179 + 152563 = 152742

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 152,742 and was likely granted around 1873.

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