Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641532, here are decompositions:

13 + 8641519 = 8641532
19 + 8641513 = 8641532
61 + 8641471 = 8641532
79 + 8641453 = 8641532
103 + 8641429 = 8641532
181 + 8641351 = 8641532
223 + 8641309 = 8641532
283 + 8641249 = 8641532

Showing the first eight; more decompositions exist.
