Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8725188, here are decompositions:

5 + 8725183 = 8725188
11 + 8725177 = 8725188
29 + 8725159 = 8725188
41 + 8725147 = 8725188
47 + 8725141 = 8725188
89 + 8725099 = 8725188
97 + 8725091 = 8725188
137 + 8725051 = 8725188

Showing the first eight; more decompositions exist.
