Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8629164, here are decompositions:

7 + 8629157 = 8629164
23 + 8629141 = 8629164
41 + 8629123 = 8629164
101 + 8629063 = 8629164
191 + 8628973 = 8629164
197 + 8628967 = 8629164
227 + 8628937 = 8629164
241 + 8628923 = 8629164

Showing the first eight; more decompositions exist.
