Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618214, here are decompositions:

41 + 8618173 = 8618214
67 + 8618147 = 8618214
83 + 8618131 = 8618214
107 + 8618107 = 8618214
127 + 8618087 = 8618214
131 + 8618083 = 8618214
151 + 8618063 = 8618214
167 + 8618047 = 8618214

Showing the first eight; more decompositions exist.
