Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617338, here are decompositions:

  • 139 + 31617199 = 31617338
  • 157 + 31617181 = 31617338
  • 409 + 31616929 = 31617338
  • 421 + 31616917 = 31617338
  • 499 + 31616839 = 31617338
  • 631 + 31616707 = 31617338
  • 661 + 31616677 = 31617338
  • 691 + 31616647 = 31617338

Showing the first eight; more decompositions exist.
