Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491780, here are decompositions:

23 + 2147491757 = 2147491780
47 + 2147491733 = 2147491780
89 + 2147491691 = 2147491780
173 + 2147491607 = 2147491780
197 + 2147491583 = 2147491780
227 + 2147491553 = 2147491780
233 + 2147491547 = 2147491780
263 + 2147491517 = 2147491780

Showing the first eight; more decompositions exist.
