Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523504, here are decompositions:

  • 31 + 31523473 = 31523504
  • 37 + 31523467 = 31523504
  • 43 + 31523461 = 31523504
  • 97 + 31523407 = 31523504
  • 157 + 31523347 = 31523504
  • 211 + 31523293 = 31523504
  • 277 + 31523227 = 31523504
  • 283 + 31523221 = 31523504

Showing the first eight; more decompositions exist.
