Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622410, here are decompositions:

  • 41 + 31622369 = 31622410
  • 137 + 31622273 = 31622410
  • 173 + 31622237 = 31622410
  • 227 + 31622183 = 31622410
  • 257 + 31622153 = 31622410
  • 263 + 31622147 = 31622410
  • 269 + 31622141 = 31622410
  • 431 + 31621979 = 31622410

Showing the first eight; more decompositions exist.
