Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563302, here are decompositions:

  • 19 + 31563283 = 31563302
  • 109 + 31563193 = 31563302
  • 139 + 31563163 = 31563302
  • 229 + 31563073 = 31563302
  • 271 + 31563031 = 31563302
  • 523 + 31562779 = 31563302
  • 619 + 31562683 = 31563302
  • 691 + 31562611 = 31563302

Showing the first eight; more decompositions exist.
