Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147383230, here are decompositions:

  • 7 + 2147383223 = 2147383230
  • 37 + 2147383193 = 2147383230
  • 53 + 2147383177 = 2147383230
  • 101 + 2147383129 = 2147383230
  • 107 + 2147383123 = 2147383230
  • 137 + 2147383093 = 2147383230
  • 151 + 2147383079 = 2147383230
  • 211 + 2147383019 = 2147383230

Showing the first eight; more decompositions exist.
