Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658108, here are decompositions:

5 + 8658103 = 8658108
7 + 8658101 = 8658108
139 + 8657969 = 8658108
181 + 8657927 = 8658108
227 + 8657881 = 8658108
257 + 8657851 = 8658108
281 + 8657827 = 8658108
307 + 8657801 = 8658108

Showing the first eight; more decompositions exist.
