Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725170, here are decompositions:

11 + 8725159 = 8725170
17 + 8725153 = 8725170
23 + 8725147 = 8725170
29 + 8725141 = 8725170
31 + 8725139 = 8725170
37 + 8725133 = 8725170
59 + 8725111 = 8725170
67 + 8725103 = 8725170

Showing the first eight; more decompositions exist.
