Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668164, here are decompositions:

7 + 8668157 = 8668164
13 + 8668151 = 8668164
23 + 8668141 = 8668164
31 + 8668133 = 8668164
53 + 8668111 = 8668164
83 + 8668081 = 8668164
97 + 8668067 = 8668164
101 + 8668063 = 8668164

Showing the first eight; more decompositions exist.
