Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620844, here are decompositions:

3 + 8620841 = 8620844
97 + 8620747 = 8620844
157 + 8620687 = 8620844
181 + 8620663 = 8620844
223 + 8620621 = 8620844
241 + 8620603 = 8620844
277 + 8620567 = 8620844
577 + 8620267 = 8620844

Showing the first eight; more decompositions exist.
