Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672898, here are decompositions:

7 + 8672891 = 8672898
29 + 8672869 = 8672898
37 + 8672861 = 8672898
67 + 8672831 = 8672898
79 + 8672819 = 8672898
97 + 8672801 = 8672898
107 + 8672791 = 8672898
109 + 8672789 = 8672898

Showing the first eight; more decompositions exist.
