Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668872, here are decompositions:

41 + 8668831 = 8668872
59 + 8668813 = 8668872
71 + 8668801 = 8668872
73 + 8668799 = 8668872
89 + 8668783 = 8668872
109 + 8668763 = 8668872
131 + 8668741 = 8668872
151 + 8668721 = 8668872

Showing the first eight; more decompositions exist.
