Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490890, here are decompositions:

7 + 2147490883 = 2147490890
19 + 2147490871 = 2147490890
79 + 2147490811 = 2147490890
151 + 2147490739 = 2147490890
163 + 2147490727 = 2147490890
313 + 2147490577 = 2147490890
439 + 2147490451 = 2147490890
547 + 2147490343 = 2147490890

Showing the first eight; more decompositions exist.
