Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618124, here are decompositions:

5 + 8618119 = 8618124
17 + 8618107 = 8618124
37 + 8618087 = 8618124
41 + 8618083 = 8618124
61 + 8618063 = 8618124
83 + 8618041 = 8618124
103 + 8618021 = 8618124
131 + 8617993 = 8618124

Showing the first eight; more decompositions exist.
