Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487918, here are decompositions:

11 + 2147487907 = 2147487918
19 + 2147487899 = 2147487918
47 + 2147487871 = 2147487918
89 + 2147487829 = 2147487918
101 + 2147487817 = 2147487918
137 + 2147487781 = 2147487918
139 + 2147487779 = 2147487918
167 + 2147487751 = 2147487918

Showing the first eight; more decompositions exist.

IPv4 address
