Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641524, here are decompositions:

5 + 8641519 = 8641524
7 + 8641517 = 8641524
11 + 8641513 = 8641524
53 + 8641471 = 8641524
71 + 8641453 = 8641524
103 + 8641421 = 8641524
163 + 8641361 = 8641524
173 + 8641351 = 8641524

Showing the first eight; more decompositions exist.
