Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147491678, here are decompositions:

71 + 2147491607 = 2147491678
131 + 2147491547 = 2147491678
317 + 2147491361 = 2147491678
359 + 2147491319 = 2147491678
401 + 2147491277 = 2147491678
461 + 2147491217 = 2147491678
587 + 2147491091 = 2147491678
617 + 2147491061 = 2147491678

Showing the first eight; more decompositions exist.
