Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31477256, here are decompositions:

  • 43 + 31477213 = 31477256
  • 157 + 31477099 = 31477256
  • 193 + 31477063 = 31477256
  • 199 + 31477057 = 31477256
  • 229 + 31477027 = 31477256
  • 409 + 31476847 = 31477256
  • 457 + 31476799 = 31477256
  • 523 + 31476733 = 31477256

Showing the first eight; more decompositions exist.
