Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491344, here are decompositions:

67 + 2147491277 = 2147491344
71 + 2147491273 = 2147491344
83 + 2147491261 = 2147491344
107 + 2147491237 = 2147491344
127 + 2147491217 = 2147491344
151 + 2147491193 = 2147491344
233 + 2147491111 = 2147491344
263 + 2147491081 = 2147491344

Showing the first eight; more decompositions exist.

IPv4 address
