Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490680, here are decompositions:

103 + 2147490577 = 2147490680
151 + 2147490529 = 2147490680
193 + 2147490487 = 2147490680
229 + 2147490451 = 2147490680
337 + 2147490343 = 2147490680
397 + 2147490283 = 2147490680
463 + 2147490217 = 2147490680
571 + 2147490109 = 2147490680

Showing the first eight; more decompositions exist.
