Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641608, here are decompositions:

5 + 8641603 = 8641608
37 + 8641571 = 8641608
61 + 8641547 = 8641608
67 + 8641541 = 8641608
89 + 8641519 = 8641608
137 + 8641471 = 8641608
139 + 8641469 = 8641608
179 + 8641429 = 8641608

Showing the first eight; more decompositions exist.
