Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490846, here are decompositions:

13 + 2147490833 = 2147490846
47 + 2147490799 = 2147490846
73 + 2147490773 = 2147490846
107 + 2147490739 = 2147490846
157 + 2147490689 = 2147490846
257 + 2147490589 = 2147490846
269 + 2147490577 = 2147490846
307 + 2147490539 = 2147490846

Showing the first eight; more decompositions exist.
