Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725150, here are decompositions:

3 + 8725147 = 8725150
11 + 8725139 = 8725150
17 + 8725133 = 8725150
47 + 8725103 = 8725150
59 + 8725091 = 8725150
113 + 8725037 = 8725150
167 + 8724983 = 8725150
347 + 8724803 = 8725150

Showing the first eight; more decompositions exist.
