Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 155602, here are decompositions:

  • 3 + 155599 = 155602
  • 23 + 155579 = 155602
  • 101 + 155501 = 155602
  • 149 + 155453 = 155602
  • 179 + 155423 = 155602
  • 269 + 155333 = 155602
  • 311 + 155291 = 155602
  • 383 + 155219 = 155602

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 155,602 and was likely granted around 1873.

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