Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564102, here are decompositions:

  • 23 + 31564079 = 31564102
  • 113 + 31563989 = 31564102
  • 149 + 31563953 = 31564102
  • 173 + 31563929 = 31564102
  • 191 + 31563911 = 31564102
  • 239 + 31563863 = 31564102
  • 419 + 31563683 = 31564102
  • 431 + 31563671 = 31564102

Showing the first eight; more decompositions exist.
