Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493948, here are decompositions:

11 + 2147493937 = 2147493948
29 + 2147493919 = 2147493948
59 + 2147493889 = 2147493948
97 + 2147493851 = 2147493948
101 + 2147493847 = 2147493948
107 + 2147493841 = 2147493948
137 + 2147493811 = 2147493948
239 + 2147493709 = 2147493948

Showing the first eight; more decompositions exist.
