Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622564, here are decompositions:

  • 73 + 31622491 = 31622564
  • 97 + 31622467 = 31622564
  • 271 + 31622293 = 31622564
  • 277 + 31622287 = 31622564
  • 283 + 31622281 = 31622564
  • 307 + 31622257 = 31622564
  • 397 + 31622167 = 31622564
  • 433 + 31622131 = 31622564

Showing the first eight; more decompositions exist.
