Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627164, here are decompositions:

3 + 8627161 = 8627164
11 + 8627153 = 8627164
17 + 8627147 = 8627164
23 + 8627141 = 8627164
53 + 8627111 = 8627164
83 + 8627081 = 8627164
107 + 8627057 = 8627164
113 + 8627051 = 8627164

Showing the first eight; more decompositions exist.
