Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147487020, here are decompositions:

163 + 2147486857 = 2147487020
193 + 2147486827 = 2147487020
229 + 2147486791 = 2147487020
271 + 2147486749 = 2147487020
313 + 2147486707 = 2147487020
331 + 2147486689 = 2147487020
379 + 2147486641 = 2147487020
421 + 2147486599 = 2147487020

Showing the first eight; more decompositions exist.
