Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8641548, here are decompositions:

5 + 8641543 = 8641548
7 + 8641541 = 8641548
29 + 8641519 = 8641548
31 + 8641517 = 8641548
79 + 8641469 = 8641548
127 + 8641421 = 8641548
197 + 8641351 = 8641548
199 + 8641349 = 8641548

Showing the first eight; more decompositions exist.
