Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31608188, here are decompositions:

  • 19 + 31608169 = 31608188
  • 97 + 31608091 = 31608188
  • 127 + 31608061 = 31608188
  • 151 + 31608037 = 31608188
  • 331 + 31607857 = 31608188
  • 349 + 31607839 = 31608188
  • 397 + 31607791 = 31608188
  • 499 + 31607689 = 31608188

Showing the first eight; more decompositions exist.
