Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641632, here are decompositions:

11 + 8641621 = 8641632
19 + 8641613 = 8641632
29 + 8641603 = 8641632
61 + 8641571 = 8641632
89 + 8641543 = 8641632
113 + 8641519 = 8641632
163 + 8641469 = 8641632
179 + 8641453 = 8641632

Showing the first eight; more decompositions exist.
