Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564412, here are decompositions:

  • 79 + 31564333 = 31564412
  • 151 + 31564261 = 31564412
  • 163 + 31564249 = 31564412
  • 241 + 31564171 = 31564412
  • 283 + 31564129 = 31564412
  • 433 + 31563979 = 31564412
  • 463 + 31563949 = 31564412
  • 541 + 31563871 = 31564412

Showing the first eight; more decompositions exist.
