Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494360, here are decompositions:

  • 13 + 31494347 = 31494360
  • 59 + 31494301 = 31494360
  • 67 + 31494293 = 31494360
  • 97 + 31494263 = 31494360
  • 103 + 31494257 = 31494360
  • 113 + 31494247 = 31494360
  • 181 + 31494179 = 31494360
  • 199 + 31494161 = 31494360

Showing the first eight; more decompositions exist.
