Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490186, here are decompositions:

97 + 2147490089 = 2147490186
109 + 2147490077 = 2147490186
229 + 2147489957 = 2147490186
239 + 2147489947 = 2147490186
269 + 2147489917 = 2147490186
277 + 2147489909 = 2147490186
313 + 2147489873 = 2147490186
337 + 2147489849 = 2147490186

Showing the first eight; more decompositions exist.
