Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700146, here are decompositions:

67 + 8700079 = 8700146
109 + 8700037 = 8700146
127 + 8700019 = 8700146
139 + 8700007 = 8700146
193 + 8699953 = 8700146
199 + 8699947 = 8700146
223 + 8699923 = 8700146
229 + 8699917 = 8700146

Showing the first eight; more decompositions exist.
