Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618160, here are decompositions:

11 + 8618149 = 8618160
13 + 8618147 = 8618160
29 + 8618131 = 8618160
41 + 8618119 = 8618160
53 + 8618107 = 8618160
71 + 8618089 = 8618160
73 + 8618087 = 8618160
97 + 8618063 = 8618160

Showing the first eight; more decompositions exist.
