Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490802, here are decompositions:

3 + 2147490799 = 2147490802
5 + 2147490797 = 2147490802
29 + 2147490773 = 2147490802
71 + 2147490731 = 2147490802
113 + 2147490689 = 2147490802
263 + 2147490539 = 2147490802
389 + 2147490413 = 2147490802
563 + 2147490239 = 2147490802

Showing the first eight; more decompositions exist.
