Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8639548, here are decompositions:

17 + 8639531 = 8639548
41 + 8639507 = 8639548
89 + 8639459 = 8639548
107 + 8639441 = 8639548
167 + 8639381 = 8639548
257 + 8639291 = 8639548
521 + 8639027 = 8639548
557 + 8638991 = 8639548

Showing the first eight; more decompositions exist.
