Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497950, here are decompositions:

  • 19 + 31497931 = 31497950
  • 67 + 31497883 = 31497950
  • 79 + 31497871 = 31497950
  • 193 + 31497757 = 31497950
  • 199 + 31497751 = 31497950
  • 223 + 31497727 = 31497950
  • 229 + 31497721 = 31497950
  • 271 + 31497679 = 31497950

Showing the first eight; more decompositions exist.
