Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524170, here are decompositions:

  • 3 + 31524167 = 31524170
  • 37 + 31524133 = 31524170
  • 79 + 31524091 = 31524170
  • 127 + 31524043 = 31524170
  • 157 + 31524013 = 31524170
  • 229 + 31523941 = 31524170
  • 331 + 31523839 = 31524170
  • 367 + 31523803 = 31524170

Showing the first eight; more decompositions exist.
