Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668242, here are decompositions:

41 + 8668201 = 8668242
101 + 8668141 = 8668242
109 + 8668133 = 8668242
131 + 8668111 = 8668242
179 + 8668063 = 8668242
181 + 8668061 = 8668242
199 + 8668043 = 8668242
211 + 8668031 = 8668242

Showing the first eight; more decompositions exist.
