Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490118, here are decompositions:

29 + 2147490089 = 2147490118
41 + 2147490077 = 2147490118
107 + 2147490011 = 2147490118
149 + 2147489969 = 2147490118
269 + 2147489849 = 2147490118
401 + 2147489717 = 2147490118
419 + 2147489699 = 2147490118
467 + 2147489651 = 2147490118

Showing the first eight; more decompositions exist.
