Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658078, here are decompositions:

19 + 8658059 = 8658078
61 + 8658017 = 8658078
109 + 8657969 = 8658078
151 + 8657927 = 8658078
197 + 8657881 = 8658078
227 + 8657851 = 8658078
229 + 8657849 = 8658078
251 + 8657827 = 8658078

Showing the first eight; more decompositions exist.
