Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700270, here are decompositions:

13 + 8700257 = 8700270
17 + 8700253 = 8700270
31 + 8700239 = 8700270
101 + 8700169 = 8700270
109 + 8700161 = 8700270
149 + 8700121 = 8700270
157 + 8700113 = 8700270
191 + 8700079 = 8700270

Showing the first eight; more decompositions exist.
