Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700140, here are decompositions:

19 + 8700121 = 8700140
61 + 8700079 = 8700140
103 + 8700037 = 8700140
109 + 8700031 = 8700140
139 + 8700001 = 8700140
181 + 8699959 = 8700140
193 + 8699947 = 8700140
223 + 8699917 = 8700140

Showing the first eight; more decompositions exist.
