Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700126, here are decompositions:

5 + 8700121 = 8700126
13 + 8700113 = 8700126
47 + 8700079 = 8700126
67 + 8700059 = 8700126
79 + 8700047 = 8700126
89 + 8700037 = 8700126
107 + 8700019 = 8700126
157 + 8699969 = 8700126

Showing the first eight; more decompositions exist.
