Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489976, here are decompositions:

7 + 2147489969 = 2147489976
19 + 2147489957 = 2147489976
29 + 2147489947 = 2147489976
59 + 2147489917 = 2147489976
67 + 2147489909 = 2147489976
103 + 2147489873 = 2147489976
127 + 2147489849 = 2147489976
157 + 2147489819 = 2147489976

Showing the first eight; more decompositions exist.
