Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490340, here are decompositions:

101 + 2147490239 = 2147490340
179 + 2147490161 = 2147490340
251 + 2147490089 = 2147490340
263 + 2147490077 = 2147490340
383 + 2147489957 = 2147490340
431 + 2147489909 = 2147490340
467 + 2147489873 = 2147490340
491 + 2147489849 = 2147490340

Showing the first eight; more decompositions exist.
