Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487556, here are decompositions:

47 + 2147487509 = 2147487556
83 + 2147487473 = 2147487556
107 + 2147487449 = 2147487556
197 + 2147487359 = 2147487556
353 + 2147487203 = 2147487556
443 + 2147487113 = 2147487556
479 + 2147487077 = 2147487556
587 + 2147486969 = 2147487556

Showing the first eight; more decompositions exist.
