Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669148, here are decompositions:

31 + 8669117 = 8669148
41 + 8669107 = 8669148
107 + 8669041 = 8669148
181 + 8668967 = 8669148
197 + 8668951 = 8669148
251 + 8668897 = 8669148
311 + 8668837 = 8669148
317 + 8668831 = 8669148

Showing the first eight; more decompositions exist.
