Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8620824, here are decompositions:

67 + 8620757 = 8620824
97 + 8620727 = 8620824
101 + 8620723 = 8620824
103 + 8620721 = 8620824
137 + 8620687 = 8620824
151 + 8620673 = 8620824
193 + 8620631 = 8620824
257 + 8620567 = 8620824

Showing the first eight; more decompositions exist.
