Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147488958, here are decompositions:

379 + 2147488579 = 2147488958
541 + 2147488417 = 2147488958
547 + 2147488411 = 2147488958
577 + 2147488381 = 2147488958
709 + 2147488249 = 2147488958
787 + 2147488171 = 2147488958
1051 + 2147487907 = 2147488958
1087 + 2147487871 = 2147488958

Showing the first eight; more decompositions exist.
