Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523534, here are decompositions:

  • 13 + 31523521 = 31523534
  • 61 + 31523473 = 31523534
  • 67 + 31523467 = 31523534
  • 73 + 31523461 = 31523534
  • 127 + 31523407 = 31523534
  • 241 + 31523293 = 31523534
  • 283 + 31523251 = 31523534
  • 307 + 31523227 = 31523534

Showing the first eight; more decompositions exist.
