Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539226, here are decompositions:

  • 83 + 31539143 = 31539226
  • 137 + 31539089 = 31539226
  • 179 + 31539047 = 31539226
  • 239 + 31538987 = 31539226
  • 419 + 31538807 = 31539226
  • 647 + 31538579 = 31539226
  • 1019 + 31538207 = 31539226
  • 1163 + 31538063 = 31539226

Showing the first eight; more decompositions exist.
