Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8644078, here are decompositions:

17 + 8644061 = 8644078
29 + 8644049 = 8644078
59 + 8644019 = 8644078
137 + 8643941 = 8644078
227 + 8643851 = 8644078
239 + 8643839 = 8644078
257 + 8643821 = 8644078
281 + 8643797 = 8644078

Showing the first eight; more decompositions exist.
