Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492146, here are decompositions:

389 + 2147491757 = 2147492146
563 + 2147491583 = 2147492146
587 + 2147491559 = 2147492146
593 + 2147491553 = 2147492146
599 + 2147491547 = 2147492146
743 + 2147491403 = 2147492146
797 + 2147491349 = 2147492146
827 + 2147491319 = 2147492146

Showing the first eight; more decompositions exist.
