Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641488, here are decompositions:

17 + 8641471 = 8641488
19 + 8641469 = 8641488
59 + 8641429 = 8641488
67 + 8641421 = 8641488
127 + 8641361 = 8641488
137 + 8641351 = 8641488
139 + 8641349 = 8641488
157 + 8641331 = 8641488

Showing the first eight; more decompositions exist.
