Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491178, here are decompositions:

67 + 2147491111 = 2147491178
97 + 2147491081 = 2147491178
109 + 2147491069 = 2147491178
181 + 2147490997 = 2147491178
211 + 2147490967 = 2147491178
307 + 2147490871 = 2147491178
367 + 2147490811 = 2147491178
379 + 2147490799 = 2147491178

Showing the first eight; more decompositions exist.

IPv4 address
