Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31539326, here are decompositions:

  • 37 + 31539289 = 31539326
  • 43 + 31539283 = 31539326
  • 97 + 31539229 = 31539326
  • 163 + 31539163 = 31539326
  • 283 + 31539043 = 31539326
  • 439 + 31538887 = 31539326
  • 499 + 31538827 = 31539326
  • 547 + 31538779 = 31539326

Showing the first eight; more decompositions exist.
