Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483220, here are decompositions:

  • 41 + 2147483179 = 2147483220
  • 83 + 2147483137 = 2147483220
  • 97 + 2147483123 = 2147483220
  • 151 + 2147483069 = 2147483220
  • 167 + 2147483053 = 2147483220
  • 191 + 2147483029 = 2147483220
  • 269 + 2147482951 = 2147483220
  • 271 + 2147482949 = 2147483220

Showing the first eight; more decompositions exist.
