Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621604, here are decompositions:

23 + 8621581 = 8621604
53 + 8621551 = 8621604
113 + 8621491 = 8621604
127 + 8621477 = 8621604
137 + 8621467 = 8621604
151 + 8621453 = 8621604
191 + 8621413 = 8621604
193 + 8621411 = 8621604

Showing the first eight; more decompositions exist.
