Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8601646, here are decompositions:

5 + 8601641 = 8601646
17 + 8601629 = 8601646
59 + 8601587 = 8601646
89 + 8601557 = 8601646
197 + 8601449 = 8601646
257 + 8601389 = 8601646
353 + 8601293 = 8601646
503 + 8601143 = 8601646

Showing the first eight; more decompositions exist.
