Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147468918, here are decompositions:

31 + 2147468887 = 2147468918
37 + 2147468881 = 2147468918
109 + 2147468809 = 2147468918
139 + 2147468779 = 2147468918
421 + 2147468497 = 2147468918
487 + 2147468431 = 2147468918
577 + 2147468341 = 2147468918
601 + 2147468317 = 2147468918

Showing the first eight; more decompositions exist.
