Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605374, here are decompositions:

  • 13 + 31605361 = 31605374
  • 103 + 31605271 = 31605374
  • 127 + 31605247 = 31605374
  • 193 + 31605181 = 31605374
  • 277 + 31605097 = 31605374
  • 373 + 31605001 = 31605374
  • 571 + 31604803 = 31605374
  • 607 + 31604767 = 31605374

Showing the first eight; more decompositions exist.
