Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490740, here are decompositions:

13 + 2147490727 = 2147490740
151 + 2147490589 = 2147490740
163 + 2147490577 = 2147490740
211 + 2147490529 = 2147490740
277 + 2147490463 = 2147490740
379 + 2147490361 = 2147490740
397 + 2147490343 = 2147490740
457 + 2147490283 = 2147490740

Showing the first eight; more decompositions exist.
