Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563314, here are decompositions:

  • 31 + 31563283 = 31563314
  • 37 + 31563277 = 31563314
  • 61 + 31563253 = 31563314
  • 127 + 31563187 = 31563314
  • 151 + 31563163 = 31563314
  • 241 + 31563073 = 31563314
  • 271 + 31563043 = 31563314
  • 283 + 31563031 = 31563314

Showing the first eight; more decompositions exist.
