Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31544294, here are decompositions:

  • 13 + 31544281 = 31544294
  • 73 + 31544221 = 31544294
  • 127 + 31544167 = 31544294
  • 163 + 31544131 = 31544294
  • 241 + 31544053 = 31544294
  • 283 + 31544011 = 31544294
  • 307 + 31543987 = 31544294
  • 367 + 31543927 = 31544294

Showing the first eight; more decompositions exist.
