Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564264, here are decompositions:

  • 3 + 31564261 = 31564264
  • 23 + 31564241 = 31564264
  • 101 + 31564163 = 31564264
  • 107 + 31564157 = 31564264
  • 131 + 31564133 = 31564264
  • 311 + 31563953 = 31564264
  • 317 + 31563947 = 31564264
  • 353 + 31563911 = 31564264

Showing the first eight; more decompositions exist.
