Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147497888, here are decompositions:

131 + 2147497757 = 2147497888
191 + 2147497697 = 2147497888
197 + 2147497691 = 2147497888
227 + 2147497661 = 2147497888
317 + 2147497571 = 2147497888
947 + 2147496941 = 2147497888
971 + 2147496917 = 2147497888
1049 + 2147496839 = 2147497888

Showing the first eight; more decompositions exist.
