Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470944, here are decompositions:

  • 3 + 31470941 = 31470944
  • 31 + 31470913 = 31470944
  • 97 + 31470847 = 31470944
  • 151 + 31470793 = 31470944
  • 157 + 31470787 = 31470944
  • 163 + 31470781 = 31470944
  • 223 + 31470721 = 31470944
  • 283 + 31470661 = 31470944

Showing the first eight; more decompositions exist.
