Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8658164, here are decompositions:

3 + 8658161 = 8658164
61 + 8658103 = 8658164
181 + 8657983 = 8658164
241 + 8657923 = 8658164
283 + 8657881 = 8658164
313 + 8657851 = 8658164
331 + 8657833 = 8658164
337 + 8657827 = 8658164

Showing the first eight; more decompositions exist.
