Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490442, here are decompositions:

29 + 2147490413 = 2147490442
179 + 2147490263 = 2147490442
281 + 2147490161 = 2147490442
353 + 2147490089 = 2147490442
389 + 2147490053 = 2147490442
431 + 2147490011 = 2147490442
569 + 2147489873 = 2147490442
593 + 2147489849 = 2147490442

Showing the first eight; more decompositions exist.
