Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621626, here are decompositions:

3 + 8621623 = 8621626
17 + 8621609 = 8621626
149 + 8621477 = 8621626
173 + 8621453 = 8621626
197 + 8621429 = 8621626
317 + 8621309 = 8621626
383 + 8621243 = 8621626
389 + 8621237 = 8621626

Showing the first eight; more decompositions exist.
