Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523360, here are decompositions:

  • 13 + 31523347 = 31523360
  • 31 + 31523329 = 31523360
  • 67 + 31523293 = 31523360
  • 109 + 31523251 = 31523360
  • 139 + 31523221 = 31523360
  • 151 + 31523209 = 31523360
  • 199 + 31523161 = 31523360
  • 229 + 31523131 = 31523360

Showing the first eight; more decompositions exist.
