Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489982, here are decompositions:

13 + 2147489969 = 2147489982
41 + 2147489941 = 2147489982
73 + 2147489909 = 2147489982
83 + 2147489899 = 2147489982
109 + 2147489873 = 2147489982
139 + 2147489843 = 2147489982
163 + 2147489819 = 2147489982
269 + 2147489713 = 2147489982

Showing the first eight; more decompositions exist.
