Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617300, here are decompositions:

  • 7 + 31617293 = 31617300
  • 17 + 31617283 = 31617300
  • 19 + 31617281 = 31617300
  • 31 + 31617269 = 31617300
  • 47 + 31617253 = 31617300
  • 61 + 31617239 = 31617300
  • 101 + 31617199 = 31617300
  • 151 + 31617149 = 31617300

Showing the first eight; more decompositions exist.
