Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31542336, here are decompositions:

  • 13 + 31542323 = 31542336
  • 103 + 31542233 = 31542336
  • 107 + 31542229 = 31542336
  • 139 + 31542197 = 31542336
  • 173 + 31542163 = 31542336
  • 223 + 31542113 = 31542336
  • 233 + 31542103 = 31542336
  • 269 + 31542067 = 31542336

Showing the first eight; more decompositions exist.
