Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147493290, here are decompositions:

13 + 2147493277 = 2147493290
181 + 2147493109 = 2147493290
211 + 2147493079 = 2147493290
331 + 2147492959 = 2147493290
367 + 2147492923 = 2147493290
619 + 2147492671 = 2147493290
739 + 2147492551 = 2147493290
751 + 2147492539 = 2147493290

Showing the first eight; more decompositions exist.
