Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147490650, here are decompositions:

61 + 2147490589 = 2147490650
73 + 2147490577 = 2147490650
163 + 2147490487 = 2147490650
199 + 2147490451 = 2147490650
307 + 2147490343 = 2147490650
367 + 2147490283 = 2147490650
421 + 2147490229 = 2147490650
433 + 2147490217 = 2147490650

Showing the first eight; more decompositions exist.
