Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491914, here are decompositions:

11 + 2147491903 = 2147491914
17 + 2147491897 = 2147491914
83 + 2147491831 = 2147491914
157 + 2147491757 = 2147491914
181 + 2147491733 = 2147491914
223 + 2147491691 = 2147491914
307 + 2147491607 = 2147491914
311 + 2147491603 = 2147491914

Showing the first eight; more decompositions exist.
