Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522260, here are decompositions:

  • 13 + 31522247 = 31522260
  • 17 + 31522243 = 31522260
  • 19 + 31522241 = 31522260
  • 31 + 31522229 = 31522260
  • 41 + 31522219 = 31522260
  • 53 + 31522207 = 31522260
  • 79 + 31522181 = 31522260
  • 131 + 31522129 = 31522260

Showing the first eight; more decompositions exist.
