Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641662, here are decompositions:

11 + 8641651 = 8641662
19 + 8641643 = 8641662
31 + 8641631 = 8641662
41 + 8641621 = 8641662
59 + 8641603 = 8641662
149 + 8641513 = 8641662
191 + 8641471 = 8641662
193 + 8641469 = 8641662

Showing the first eight; more decompositions exist.
