Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147473658, here are decompositions:

79 + 2147473579 = 2147473658
181 + 2147473477 = 2147473658
229 + 2147473429 = 2147473658
307 + 2147473351 = 2147473658
367 + 2147473291 = 2147473658
541 + 2147473117 = 2147473658
907 + 2147472751 = 2147473658
1237 + 2147472421 = 2147473658

Showing the first eight; more decompositions exist.
