Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622612, here are decompositions:

  • 13 + 31622599 = 31622612
  • 103 + 31622509 = 31622612
  • 139 + 31622473 = 31622612
  • 223 + 31622389 = 31622612
  • 331 + 31622281 = 31622612
  • 433 + 31622179 = 31622612
  • 499 + 31622113 = 31622612
  • 631 + 31621981 = 31622612

Showing the first eight; more decompositions exist.
