Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618184, here are decompositions:

11 + 8618173 = 8618184
37 + 8618147 = 8618184
53 + 8618131 = 8618184
97 + 8618087 = 8618184
101 + 8618083 = 8618184
137 + 8618047 = 8618184
151 + 8618033 = 8618184
163 + 8618021 = 8618184

Showing the first eight; more decompositions exist.
