Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492918, here are decompositions:

367 + 2147492551 = 2147492918
379 + 2147492539 = 2147492918
397 + 2147492521 = 2147492918
547 + 2147492371 = 2147492918
601 + 2147492317 = 2147492918
619 + 2147492299 = 2147492918
757 + 2147492161 = 2147492918
1021 + 2147491897 = 2147492918

Showing the first eight; more decompositions exist.
