Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488874, here are decompositions:

7 + 2147488867 = 2147488874
331 + 2147488543 = 2147488874
457 + 2147488417 = 2147488874
463 + 2147488411 = 2147488874
541 + 2147488333 = 2147488874
967 + 2147487907 = 2147488874
1093 + 2147487781 = 2147488874
1117 + 2147487757 = 2147488874

Showing the first eight; more decompositions exist.
