Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648164, here are decompositions:

53 + 8648111 = 8648164
71 + 8648093 = 8648164
131 + 8648033 = 8648164
167 + 8647997 = 8648164
197 + 8647967 = 8648164
227 + 8647937 = 8648164
251 + 8647913 = 8648164
347 + 8647817 = 8648164

Showing the first eight; more decompositions exist.
