Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524318, here are decompositions:

  • 17 + 31524301 = 31524318
  • 41 + 31524277 = 31524318
  • 47 + 31524271 = 31524318
  • 61 + 31524257 = 31524318
  • 151 + 31524167 = 31524318
  • 157 + 31524161 = 31524318
  • 211 + 31524107 = 31524318
  • 227 + 31524091 = 31524318

Showing the first eight; more decompositions exist.
