Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488878, here are decompositions:

11 + 2147488867 = 2147488878
19 + 2147488859 = 2147488878
127 + 2147488751 = 2147488878
137 + 2147488741 = 2147488878
151 + 2147488727 = 2147488878
449 + 2147488429 = 2147488878
461 + 2147488417 = 2147488878
467 + 2147488411 = 2147488878

Showing the first eight; more decompositions exist.
