Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668152, here are decompositions:

11 + 8668141 = 8668152
19 + 8668133 = 8668152
41 + 8668111 = 8668152
71 + 8668081 = 8668152
79 + 8668073 = 8668152
89 + 8668063 = 8668152
109 + 8668043 = 8668152
151 + 8668001 = 8668152

Showing the first eight; more decompositions exist.
