Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485980, here are decompositions:

11 + 2147485969 = 2147485980
41 + 2147485939 = 2147485980
53 + 2147485927 = 2147485980
67 + 2147485913 = 2147485980
83 + 2147485897 = 2147485980
103 + 2147485877 = 2147485980
109 + 2147485871 = 2147485980
113 + 2147485867 = 2147485980

Showing the first eight; more decompositions exist.
