Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8632872, here are decompositions:

41 + 8632831 = 8632872
43 + 8632829 = 8632872
71 + 8632801 = 8632872
113 + 8632759 = 8632872
173 + 8632699 = 8632872
211 + 8632661 = 8632872
223 + 8632649 = 8632872
251 + 8632621 = 8632872

Showing the first eight; more decompositions exist.
