Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618148, here are decompositions:

17 + 8618131 = 8618148
29 + 8618119 = 8618148
41 + 8618107 = 8618148
59 + 8618089 = 8618148
61 + 8618087 = 8618148
89 + 8618059 = 8618148
101 + 8618047 = 8618148
107 + 8618041 = 8618148

Showing the first eight; more decompositions exist.
