Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31564342, here are decompositions:

  • 11 + 31564331 = 31564342
  • 71 + 31564271 = 31564342
  • 101 + 31564241 = 31564342
  • 113 + 31564229 = 31564342
  • 179 + 31564163 = 31564342
  • 239 + 31564103 = 31564342
  • 263 + 31564079 = 31564342
  • 353 + 31563989 = 31564342

Showing the first eight; more decompositions exist.
