Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488918, here are decompositions:

5 + 2147488913 = 2147488918
11 + 2147488907 = 2147488918
59 + 2147488859 = 2147488918
167 + 2147488751 = 2147488918
191 + 2147488727 = 2147488918
227 + 2147488691 = 2147488918
359 + 2147488559 = 2147488918
401 + 2147488517 = 2147488918

Showing the first eight; more decompositions exist.
