Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8659072, here are decompositions:

5 + 8659067 = 8659072
11 + 8659061 = 8659072
29 + 8659043 = 8659072
53 + 8659019 = 8659072
83 + 8658989 = 8659072
89 + 8658983 = 8659072
113 + 8658959 = 8659072
131 + 8658941 = 8659072

Showing the first eight; more decompositions exist.
