Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8618228, here are decompositions:

7 + 8618221 = 8618228
79 + 8618149 = 8618228
97 + 8618131 = 8618228
109 + 8618119 = 8618228
139 + 8618089 = 8618228
181 + 8618047 = 8618228
547 + 8617681 = 8618228
601 + 8617627 = 8618228

Showing the first eight; more decompositions exist.
