Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516270, here are decompositions:

  • 17 + 31516253 = 31516270
  • 29 + 31516241 = 31516270
  • 113 + 31516157 = 31516270
  • 131 + 31516139 = 31516270
  • 167 + 31516103 = 31516270
  • 263 + 31516007 = 31516270
  • 281 + 31515989 = 31516270
  • 389 + 31515881 = 31516270

Showing the first eight; more decompositions exist.
