Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493406, here are decompositions:

353 + 2147493053 = 2147493406
389 + 2147493017 = 2147493406
467 + 2147492939 = 2147493406
563 + 2147492843 = 2147493406
647 + 2147492759 = 2147493406
797 + 2147492609 = 2147493406
809 + 2147492597 = 2147493406
977 + 2147492429 = 2147493406

Showing the first eight; more decompositions exist.
