Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700218, here are decompositions:

97 + 8700121 = 8700218
139 + 8700079 = 8700218
181 + 8700037 = 8700218
199 + 8700019 = 8700218
211 + 8700007 = 8700218
271 + 8699947 = 8700218
367 + 8699851 = 8700218
487 + 8699731 = 8700218

Showing the first eight; more decompositions exist.
