Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618252, here are decompositions:

31 + 8618221 = 8618252
79 + 8618173 = 8618252
103 + 8618149 = 8618252
163 + 8618089 = 8618252
193 + 8618059 = 8618252
211 + 8618041 = 8618252
499 + 8617753 = 8618252
571 + 8617681 = 8618252

Showing the first eight; more decompositions exist.
