Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700158, here are decompositions:

37 + 8700121 = 8700158
79 + 8700079 = 8700158
127 + 8700031 = 8700158
139 + 8700019 = 8700158
151 + 8700007 = 8700158
157 + 8700001 = 8700158
199 + 8699959 = 8700158
211 + 8699947 = 8700158

Showing the first eight; more decompositions exist.
