Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147483178, here are decompositions:

  • 7 + 2147483171 = 2147483178
  • 41 + 2147483137 = 2147483178
  • 101 + 2147483077 = 2147483178
  • 109 + 2147483069 = 2147483178
  • 149 + 2147483029 = 2147483178
  • 227 + 2147482951 = 2147483178
  • 229 + 2147482949 = 2147483178
  • 241 + 2147482937 = 2147483178

Showing the first eight; more decompositions exist.
