Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524228, here are decompositions:

  • 5 + 31524223 = 31524228
  • 31 + 31524197 = 31524228
  • 61 + 31524167 = 31524228
  • 67 + 31524161 = 31524228
  • 137 + 31524091 = 31524228
  • 179 + 31524049 = 31524228
  • 181 + 31524047 = 31524228
  • 311 + 31523917 = 31524228

Showing the first eight; more decompositions exist.
