Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485478, here are decompositions:

31 + 2147485447 = 2147485478
67 + 2147485411 = 2147485478
97 + 2147485381 = 2147485478
109 + 2147485369 = 2147485478
211 + 2147485267 = 2147485478
277 + 2147485201 = 2147485478
337 + 2147485141 = 2147485478
421 + 2147485057 = 2147485478

Showing the first eight; more decompositions exist.
