Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491090, here are decompositions:

23 + 2147491067 = 2147491090
29 + 2147491061 = 2147491090
47 + 2147491043 = 2147491090
53 + 2147491037 = 2147491090
71 + 2147491019 = 2147491090
83 + 2147491007 = 2147491090
89 + 2147491001 = 2147491090
137 + 2147490953 = 2147491090

Showing the first eight; more decompositions exist.

IPv4 address
