Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564054, here are decompositions:

  • 3 + 31564051 = 31564054
  • 101 + 31563953 = 31564054
  • 107 + 31563947 = 31564054
  • 113 + 31563941 = 31564054
  • 173 + 31563881 = 31564054
  • 191 + 31563863 = 31564054
  • 227 + 31563827 = 31564054
  • 281 + 31563773 = 31564054

Showing the first eight; more decompositions exist.
