Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147478178, here are decompositions:

29 + 2147478149 = 2147478178
89 + 2147478089 = 2147478178
317 + 2147477861 = 2147478178
479 + 2147477699 = 2147478178
491 + 2147477687 = 2147478178
647 + 2147477531 = 2147478178
929 + 2147477249 = 2147478178
941 + 2147477237 = 2147478178

Showing the first eight; more decompositions exist.
