Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725158, here are decompositions:

5 + 8725153 = 8725158
11 + 8725147 = 8725158
17 + 8725141 = 8725158
19 + 8725139 = 8725158
47 + 8725111 = 8725158
59 + 8725099 = 8725158
67 + 8725091 = 8725158
107 + 8725051 = 8725158

Showing the first eight; more decompositions exist.
