Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31512084, here are decompositions:

  • 13 + 31512071 = 31512084
  • 47 + 31512037 = 31512084
  • 61 + 31512023 = 31512084
  • 67 + 31512017 = 31512084
  • 73 + 31512011 = 31512084
  • 103 + 31511981 = 31512084
  • 151 + 31511933 = 31512084
  • 157 + 31511927 = 31512084

Showing the first eight; more decompositions exist.
