Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8600644, here are decompositions:

5 + 8600639 = 8600644
11 + 8600633 = 8600644
23 + 8600621 = 8600644
53 + 8600591 = 8600644
167 + 8600477 = 8600644
233 + 8600411 = 8600644
251 + 8600393 = 8600644
431 + 8600213 = 8600644

Showing the first eight; more decompositions exist.
