Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618156, here are decompositions:

7 + 8618149 = 8618156
37 + 8618119 = 8618156
67 + 8618089 = 8618156
73 + 8618083 = 8618156
97 + 8618059 = 8618156
109 + 8618047 = 8618156
163 + 8617993 = 8618156
223 + 8617933 = 8618156

Showing the first eight; more decompositions exist.
