Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8728152, here are decompositions:

5 + 8728147 = 8728152
23 + 8728129 = 8728152
73 + 8728079 = 8728152
79 + 8728073 = 8728152
163 + 8727989 = 8728152
239 + 8727913 = 8728152
281 + 8727871 = 8728152
373 + 8727779 = 8728152

Showing the first eight; more decompositions exist.
