Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522312, here are decompositions:

  • 71 + 31522241 = 31522312
  • 83 + 31522229 = 31522312
  • 131 + 31522181 = 31522312
  • 251 + 31522061 = 31522312
  • 293 + 31522019 = 31522312
  • 359 + 31521953 = 31522312
  • 449 + 31521863 = 31522312
  • 461 + 31521851 = 31522312

Showing the first eight; more decompositions exist.
