Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491354, here are decompositions:

5 + 2147491349 = 2147491354
11 + 2147491343 = 2147491354
131 + 2147491223 = 2147491354
137 + 2147491217 = 2147491354
227 + 2147491127 = 2147491354
263 + 2147491091 = 2147491354
293 + 2147491061 = 2147491354
311 + 2147491043 = 2147491354

Showing the first eight; more decompositions exist.
