Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490686, here are decompositions:

97 + 2147490589 = 2147490686
109 + 2147490577 = 2147490686
157 + 2147490529 = 2147490686
199 + 2147490487 = 2147490686
223 + 2147490463 = 2147490686
457 + 2147490229 = 2147490686
577 + 2147490109 = 2147490686
739 + 2147489947 = 2147490686

Showing the first eight; more decompositions exist.
