Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632820, here are decompositions:

3 + 8632817 = 8632820
19 + 8632801 = 8632820
43 + 8632777 = 8632820
61 + 8632759 = 8632820
103 + 8632717 = 8632820
199 + 8632621 = 8632820
211 + 8632609 = 8632820
223 + 8632597 = 8632820

Showing the first eight; more decompositions exist.
