Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622480, here are decompositions:

  • 7 + 31622473 = 31622480
  • 13 + 31622467 = 31622480
  • 103 + 31622377 = 31622480
  • 193 + 31622287 = 31622480
  • 199 + 31622281 = 31622480
  • 223 + 31622257 = 31622480
  • 313 + 31622167 = 31622480
  • 349 + 31622131 = 31622480

Showing the first eight; more decompositions exist.
