Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618226, here are decompositions:

5 + 8618221 = 8618226
13 + 8618213 = 8618226
53 + 8618173 = 8618226
79 + 8618147 = 8618226
107 + 8618119 = 8618226
137 + 8618089 = 8618226
139 + 8618087 = 8618226
163 + 8618063 = 8618226

Showing the first eight; more decompositions exist.
