Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668844, here are decompositions:

7 + 8668837 = 8668844
13 + 8668831 = 8668844
31 + 8668813 = 8668844
43 + 8668801 = 8668844
61 + 8668783 = 8668844
103 + 8668741 = 8668844
157 + 8668687 = 8668844
421 + 8668423 = 8668844

Showing the first eight; more decompositions exist.
