Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31620522, here are decompositions:

  • 5 + 31620517 = 31620522
  • 23 + 31620499 = 31620522
  • 41 + 31620481 = 31620522
  • 79 + 31620443 = 31620522
  • 113 + 31620409 = 31620522
  • 163 + 31620359 = 31620522
  • 179 + 31620343 = 31620522
  • 223 + 31620299 = 31620522

Showing the first eight; more decompositions exist.
