Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490788, here are decompositions:

19 + 2147490769 = 2147490788
61 + 2147490727 = 2147490788
199 + 2147490589 = 2147490788
211 + 2147490577 = 2147490788
337 + 2147490451 = 2147490788
571 + 2147490217 = 2147490788
727 + 2147490061 = 2147490788
967 + 2147489821 = 2147490788

Showing the first eight; more decompositions exist.
