Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8671188, here are decompositions:

11 + 8671177 = 8671188
37 + 8671151 = 8671188
41 + 8671147 = 8671188
61 + 8671127 = 8671188
89 + 8671099 = 8671188
131 + 8671057 = 8671188
137 + 8671051 = 8671188
157 + 8671031 = 8671188

Showing the first eight; more decompositions exist.
