Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658028, here are decompositions:

11 + 8658017 = 8658028
59 + 8657969 = 8658028
101 + 8657927 = 8658028
179 + 8657849 = 8658028
227 + 8657801 = 8658028
257 + 8657771 = 8658028
347 + 8657681 = 8658028
389 + 8657639 = 8658028

Showing the first eight; more decompositions exist.
