Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487898, here are decompositions:

29 + 2147487869 = 2147487898
71 + 2147487827 = 2147487898
197 + 2147487701 = 2147487898
389 + 2147487509 = 2147487898
449 + 2147487449 = 2147487898
821 + 2147487077 = 2147487898
839 + 2147487059 = 2147487898
929 + 2147486969 = 2147487898

Showing the first eight; more decompositions exist.
