Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700278, here are decompositions:

109 + 8700169 = 8700278
157 + 8700121 = 8700278
199 + 8700079 = 8700278
241 + 8700037 = 8700278
271 + 8700007 = 8700278
277 + 8700001 = 8700278
331 + 8699947 = 8700278
421 + 8699857 = 8700278

Showing the first eight; more decompositions exist.
