Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490494, here are decompositions:

7 + 2147490487 = 2147490494
31 + 2147490463 = 2147490494
43 + 2147490451 = 2147490494
151 + 2147490343 = 2147490494
211 + 2147490283 = 2147490494
277 + 2147490217 = 2147490494
433 + 2147490061 = 2147490494
547 + 2147489947 = 2147490494

Showing the first eight; more decompositions exist.
