Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489964, here are decompositions:

7 + 2147489957 = 2147489964
17 + 2147489947 = 2147489964
23 + 2147489941 = 2147489964
47 + 2147489917 = 2147489964
167 + 2147489797 = 2147489964
251 + 2147489713 = 2147489964
311 + 2147489653 = 2147489964
313 + 2147489651 = 2147489964

Showing the first eight; more decompositions exist.
