Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31514028, here are decompositions:

  • 5 + 31514023 = 31514028
  • 41 + 31513987 = 31514028
  • 61 + 31513967 = 31514028
  • 71 + 31513957 = 31514028
  • 101 + 31513927 = 31514028
  • 137 + 31513891 = 31514028
  • 149 + 31513879 = 31514028
  • 151 + 31513877 = 31514028

Showing the first eight; more decompositions exist.
