Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147489306, here are decompositions:

7 + 2147489299 = 2147489306
43 + 2147489263 = 2147489306
103 + 2147489203 = 2147489306
163 + 2147489143 = 2147489306
223 + 2147489083 = 2147489306
229 + 2147489077 = 2147489306
283 + 2147489023 = 2147489306
439 + 2147488867 = 2147489306

Showing the first eight; more decompositions exist.
