Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621310, here are decompositions:

11 + 8621299 = 8621310
29 + 8621281 = 8621310
67 + 8621243 = 8621310
73 + 8621237 = 8621310
97 + 8621213 = 8621310
101 + 8621209 = 8621310
109 + 8621201 = 8621310
127 + 8621183 = 8621310

Showing the first eight; more decompositions exist.
