Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493882, here are decompositions:

19 + 2147493863 = 2147493882
29 + 2147493853 = 2147493882
31 + 2147493851 = 2147493882
41 + 2147493841 = 2147493882
71 + 2147493811 = 2147493882
109 + 2147493773 = 2147493882
151 + 2147493731 = 2147493882
173 + 2147493709 = 2147493882

Showing the first eight; more decompositions exist.
