Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668170, here are decompositions:

13 + 8668157 = 8668170
19 + 8668151 = 8668170
29 + 8668141 = 8668170
37 + 8668133 = 8668170
59 + 8668111 = 8668170
89 + 8668081 = 8668170
97 + 8668073 = 8668170
103 + 8668067 = 8668170

Showing the first eight; more decompositions exist.
