Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31545366, here are decompositions:

  • 23 + 31545343 = 31545366
  • 37 + 31545329 = 31545366
  • 43 + 31545323 = 31545366
  • 67 + 31545299 = 31545366
  • 79 + 31545287 = 31545366
  • 269 + 31545097 = 31545366
  • 283 + 31545083 = 31545366
  • 317 + 31545049 = 31545366

Showing the first eight; more decompositions exist.
