Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622510, here are decompositions:

  • 19 + 31622491 = 31622510
  • 37 + 31622473 = 31622510
  • 43 + 31622467 = 31622510
  • 163 + 31622347 = 31622510
  • 223 + 31622287 = 31622510
  • 229 + 31622281 = 31622510
  • 331 + 31622179 = 31622510
  • 379 + 31622131 = 31622510

Showing the first eight; more decompositions exist.
