Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490922, here are decompositions:

23 + 2147490899 = 2147490922
89 + 2147490833 = 2147490922
149 + 2147490773 = 2147490922
191 + 2147490731 = 2147490922
233 + 2147490689 = 2147490922
263 + 2147490659 = 2147490922
383 + 2147490539 = 2147490922
509 + 2147490413 = 2147490922

Showing the first eight; more decompositions exist.
