Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728554, here are decompositions:

5 + 8728549 = 8728554
41 + 8728513 = 8728554
71 + 8728483 = 8728554
73 + 8728481 = 8728554
83 + 8728471 = 8728554
97 + 8728457 = 8728554
127 + 8728427 = 8728554
157 + 8728397 = 8728554

Showing the first eight; more decompositions exist.
