Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621364, here are decompositions:

83 + 8621281 = 8621364
127 + 8621237 = 8621364
151 + 8621213 = 8621364
163 + 8621201 = 8621364
181 + 8621183 = 8621364
211 + 8621153 = 8621364
263 + 8621101 = 8621364
277 + 8621087 = 8621364

Showing the first eight; more decompositions exist.
