Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700086, here are decompositions:

7 + 8700079 = 8700086
67 + 8700019 = 8700086
79 + 8700007 = 8700086
127 + 8699959 = 8700086
139 + 8699947 = 8700086
163 + 8699923 = 8700086
193 + 8699893 = 8700086
229 + 8699857 = 8700086

Showing the first eight; more decompositions exist.
