Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 2147492866, here are decompositions:

23 + 2147492843 = 2147492866
107 + 2147492759 = 2147492866
227 + 2147492639 = 2147492866
257 + 2147492609 = 2147492866
269 + 2147492597 = 2147492866
419 + 2147492447 = 2147492866
479 + 2147492387 = 2147492866
569 + 2147492297 = 2147492866

Showing the first eight; more decompositions exist.
