Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8643548, here are decompositions:

61 + 8643487 = 8643548
139 + 8643409 = 8643548
181 + 8643367 = 8643548
211 + 8643337 = 8643548
241 + 8643307 = 8643548
337 + 8643211 = 8643548
349 + 8643199 = 8643548
367 + 8643181 = 8643548

Showing the first eight; more decompositions exist.
