Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622470, here are decompositions:

  • 3 + 31622467 = 31622470
  • 41 + 31622429 = 31622470
  • 101 + 31622369 = 31622470
  • 197 + 31622273 = 31622470
  • 233 + 31622237 = 31622470
  • 263 + 31622207 = 31622470
  • 281 + 31622189 = 31622470
  • 317 + 31622153 = 31622470

Showing the first eight; more decompositions exist.
