Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147588220, here are decompositions:

  • 17 + 2147588203 = 2147588220
  • 23 + 2147588197 = 2147588220
  • 53 + 2147588167 = 2147588220
  • 67 + 2147588153 = 2147588220
  • 97 + 2147588123 = 2147588220
  • 103 + 2147588117 = 2147588220
  • 131 + 2147588089 = 2147588220
  • 163 + 2147588057 = 2147588220

Showing the first eight; more decompositions exist.
