Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647164, here are decompositions:

7 + 8647157 = 8647164
37 + 8647127 = 8647164
41 + 8647123 = 8647164
73 + 8647091 = 8647164
101 + 8647063 = 8647164
103 + 8647061 = 8647164
137 + 8647027 = 8647164
157 + 8647007 = 8647164

Showing the first eight; more decompositions exist.
