Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522, here are decompositions:

  • 5 + 31517 = 31522
  • 11 + 31511 = 31522
  • 41 + 31481 = 31522
  • 53 + 31469 = 31522
  • 131 + 31391 = 31522
  • 251 + 31271 = 31522
  • 263 + 31259 = 31522
  • 269 + 31253 = 31522

Showing the first eight; more decompositions exist.
