Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31524290, here are decompositions:

  • 13 + 31524277 = 31524290
  • 19 + 31524271 = 31524290
  • 67 + 31524223 = 31524290
  • 97 + 31524193 = 31524290
  • 157 + 31524133 = 31524290
  • 199 + 31524091 = 31524290
  • 241 + 31524049 = 31524290
  • 277 + 31524013 = 31524290

Showing the first eight; more decompositions exist.
