Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31625896, here are decompositions:

  • 47 + 31625849 = 31625896
  • 53 + 31625843 = 31625896
  • 89 + 31625807 = 31625896
  • 173 + 31625723 = 31625896
  • 293 + 31625603 = 31625896
  • 317 + 31625579 = 31625896
  • 359 + 31625537 = 31625896
  • 389 + 31625507 = 31625896

Showing the first eight; more decompositions exist.
