Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8669154, here are decompositions:

31 + 8669123 = 8669154
37 + 8669117 = 8669154
41 + 8669113 = 8669154
47 + 8669107 = 8669154
71 + 8669083 = 8669154
83 + 8669071 = 8669154
113 + 8669041 = 8669154
127 + 8669027 = 8669154

Showing the first eight; more decompositions exist.
