Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31471136, here are decompositions:

  • 13 + 31471123 = 31471136
  • 43 + 31471093 = 31471136
  • 139 + 31470997 = 31471136
  • 223 + 31470913 = 31471136
  • 283 + 31470853 = 31471136
  • 313 + 31470823 = 31471136
  • 337 + 31470799 = 31471136
  • 349 + 31470787 = 31471136

Showing the first eight; more decompositions exist.
