Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492180, here are decompositions:

19 + 2147492161 = 2147492180
151 + 2147492029 = 2147492180
157 + 2147492023 = 2147492180
277 + 2147491903 = 2147492180
283 + 2147491897 = 2147492180
349 + 2147491831 = 2147492180
571 + 2147491609 = 2147492180
577 + 2147491603 = 2147492180

Showing the first eight; more decompositions exist.
