Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491222, here are decompositions:

3 + 2147491219 = 2147491222
5 + 2147491217 = 2147491222
29 + 2147491193 = 2147491222
83 + 2147491139 = 2147491222
131 + 2147491091 = 2147491222
179 + 2147491043 = 2147491222
269 + 2147490953 = 2147491222
389 + 2147490833 = 2147491222

Showing the first eight; more decompositions exist.

IPv4 address
