Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31523248, here are decompositions:

  • 5 + 31523243 = 31523248
  • 11 + 31523237 = 31523248
  • 17 + 31523231 = 31523248
  • 41 + 31523207 = 31523248
  • 47 + 31523201 = 31523248
  • 137 + 31523111 = 31523248
  • 149 + 31523099 = 31523248
  • 167 + 31523081 = 31523248

Showing the first eight; more decompositions exist.
