Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672928, here are decompositions:

31 + 8672897 = 8672928
37 + 8672891 = 8672928
59 + 8672869 = 8672928
67 + 8672861 = 8672928
97 + 8672831 = 8672928
107 + 8672821 = 8672928
109 + 8672819 = 8672928
127 + 8672801 = 8672928

Showing the first eight; more decompositions exist.
