Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618144, here are decompositions:

13 + 8618131 = 8618144
37 + 8618107 = 8618144
61 + 8618083 = 8618144
97 + 8618047 = 8618144
103 + 8618041 = 8618144
151 + 8617993 = 8618144
211 + 8617933 = 8618144
307 + 8617837 = 8618144

Showing the first eight; more decompositions exist.
