Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523244, here are decompositions:

  • 7 + 31523237 = 31523244
  • 13 + 31523231 = 31523244
  • 17 + 31523227 = 31523244
  • 23 + 31523221 = 31523244
  • 37 + 31523207 = 31523244
  • 43 + 31523201 = 31523244
  • 83 + 31523161 = 31523244
  • 101 + 31523143 = 31523244

Showing the first eight; more decompositions exist.
