Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523252, here are decompositions:

  • 31 + 31523221 = 31523252
  • 43 + 31523209 = 31523252
  • 109 + 31523143 = 31523252
  • 139 + 31523113 = 31523252
  • 199 + 31523053 = 31523252
  • 379 + 31522873 = 31523252
  • 619 + 31522633 = 31523252
  • 661 + 31522591 = 31523252

Showing the first eight; more decompositions exist.
