Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621394, here are decompositions:

17 + 8621377 = 8621394
113 + 8621281 = 8621394
151 + 8621243 = 8621394
157 + 8621237 = 8621394
181 + 8621213 = 8621394
193 + 8621201 = 8621394
211 + 8621183 = 8621394
241 + 8621153 = 8621394

Showing the first eight; more decompositions exist.
