Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621112, here are decompositions:

11 + 8621101 = 8621112
23 + 8621089 = 8621112
29 + 8621083 = 8621112
61 + 8621051 = 8621112
103 + 8621009 = 8621112
139 + 8620973 = 8621112
163 + 8620949 = 8621112
239 + 8620873 = 8621112

Showing the first eight; more decompositions exist.
