Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8707188, here are decompositions:

5 + 8707183 = 8707188
29 + 8707159 = 8707188
41 + 8707147 = 8707188
97 + 8707091 = 8707188
131 + 8707057 = 8707188
151 + 8707037 = 8707188
157 + 8707031 = 8707188
167 + 8707021 = 8707188

Showing the first eight; more decompositions exist.
