Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700230, here are decompositions:

37 + 8700193 = 8700230
61 + 8700169 = 8700230
109 + 8700121 = 8700230
151 + 8700079 = 8700230
193 + 8700037 = 8700230
199 + 8700031 = 8700230
211 + 8700019 = 8700230
223 + 8700007 = 8700230

Showing the first eight; more decompositions exist.
