Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4294997644, here are decompositions:

17 + 4294997627 = 4294997644
83 + 4294997561 = 4294997644
173 + 4294997471 = 4294997644
227 + 4294997417 = 4294997644
257 + 4294997387 = 4294997644
347 + 4294997297 = 4294997644
383 + 4294997261 = 4294997644
503 + 4294997141 = 4294997644

Showing the first eight; more decompositions exist.
