Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492198, here are decompositions:

37 + 2147492161 = 2147492198
367 + 2147491831 = 2147492198
499 + 2147491699 = 2147492198
601 + 2147491597 = 2147492198
661 + 2147491537 = 2147492198
829 + 2147491369 = 2147492198
937 + 2147491261 = 2147492198
997 + 2147491201 = 2147492198

Showing the first eight; more decompositions exist.
