Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522610, here are decompositions:

  • 13 + 31522597 = 31522610
  • 19 + 31522591 = 31522610
  • 61 + 31522549 = 31522610
  • 151 + 31522459 = 31522610
  • 199 + 31522411 = 31522610
  • 271 + 31522339 = 31522610
  • 283 + 31522327 = 31522610
  • 313 + 31522297 = 31522610

Showing the first eight; more decompositions exist.
