Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493338, here are decompositions:

37 + 2147493301 = 2147493338
61 + 2147493277 = 2147493338
97 + 2147493241 = 2147493338
229 + 2147493109 = 2147493338
337 + 2147493001 = 2147493338
379 + 2147492959 = 2147493338
409 + 2147492929 = 2147493338
787 + 2147492551 = 2147493338

Showing the first eight; more decompositions exist.
