Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490402, here are decompositions:

41 + 2147490361 = 2147490402
59 + 2147490343 = 2147490402
139 + 2147490263 = 2147490402
163 + 2147490239 = 2147490402
173 + 2147490229 = 2147490402
241 + 2147490161 = 2147490402
293 + 2147490109 = 2147490402
313 + 2147490089 = 2147490402

Showing the first eight; more decompositions exist.
