Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725152, here are decompositions:

5 + 8725147 = 8725152
11 + 8725141 = 8725152
13 + 8725139 = 8725152
19 + 8725133 = 8725152
41 + 8725111 = 8725152
53 + 8725099 = 8725152
61 + 8725091 = 8725152
101 + 8725051 = 8725152

Showing the first eight; more decompositions exist.
