Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621070, here are decompositions:

19 + 8621051 = 8621070
23 + 8621047 = 8621070
53 + 8621017 = 8621070
61 + 8621009 = 8621070
97 + 8620973 = 8621070
127 + 8620943 = 8621070
173 + 8620897 = 8621070
197 + 8620873 = 8621070

Showing the first eight; more decompositions exist.
