Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147485394, here are decompositions:

13 + 2147485381 = 2147485394
37 + 2147485357 = 2147485394
127 + 2147485267 = 2147485394
193 + 2147485201 = 2147485394
337 + 2147485057 = 2147485394
433 + 2147484961 = 2147485394
643 + 2147484751 = 2147485394
661 + 2147484733 = 2147485394

Showing the first eight; more decompositions exist.
