Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 154580, here are decompositions:

  • 7 + 154573 = 154580
  • 37 + 154543 = 154580
  • 79 + 154501 = 154580
  • 157 + 154423 = 154580
  • 163 + 154417 = 154580
  • 193 + 154387 = 154580
  • 211 + 154369 = 154580
  • 229 + 154351 = 154580

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 154,580 and was likely granted around 1873.

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