Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489070, here are decompositions:

11 + 2147489059 = 2147489070
47 + 2147489023 = 2147489070
53 + 2147489017 = 2147489070
73 + 2147488997 = 2147489070
151 + 2147488919 = 2147489070
157 + 2147488913 = 2147489070
163 + 2147488907 = 2147489070
211 + 2147488859 = 2147489070

Showing the first eight; more decompositions exist.
