Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621622, here are decompositions:

5 + 8621617 = 8621622
13 + 8621609 = 8621622
41 + 8621581 = 8621622
71 + 8621551 = 8621622
131 + 8621491 = 8621622
179 + 8621443 = 8621622
193 + 8621429 = 8621622
211 + 8621411 = 8621622

Showing the first eight; more decompositions exist.
