Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658072, here are decompositions:

13 + 8658059 = 8658072
29 + 8658043 = 8658072
89 + 8657983 = 8658072
103 + 8657969 = 8658072
139 + 8657933 = 8658072
149 + 8657923 = 8658072
191 + 8657881 = 8658072
223 + 8657849 = 8658072

Showing the first eight; more decompositions exist.
