Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700228, here are decompositions:

59 + 8700169 = 8700228
67 + 8700161 = 8700228
107 + 8700121 = 8700228
149 + 8700079 = 8700228
157 + 8700071 = 8700228
181 + 8700047 = 8700228
191 + 8700037 = 8700228
197 + 8700031 = 8700228

Showing the first eight; more decompositions exist.
