Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147494668, here are decompositions:

5 + 2147494663 = 2147494668
97 + 2147494571 = 2147494668
131 + 2147494537 = 2147494668
139 + 2147494529 = 2147494668
157 + 2147494511 = 2147494668
181 + 2147494487 = 2147494668
199 + 2147494469 = 2147494668
311 + 2147494357 = 2147494668

Showing the first eight; more decompositions exist.
