Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524274, here are decompositions:

  • 3 + 31524271 = 31524274
  • 17 + 31524257 = 31524274
  • 107 + 31524167 = 31524274
  • 113 + 31524161 = 31524274
  • 167 + 31524107 = 31524274
  • 227 + 31524047 = 31524274
  • 251 + 31524023 = 31524274
  • 263 + 31524011 = 31524274

Showing the first eight; more decompositions exist.
