Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672904, here are decompositions:

7 + 8672897 = 8672904
13 + 8672891 = 8672904
43 + 8672861 = 8672904
73 + 8672831 = 8672904
83 + 8672821 = 8672904
103 + 8672801 = 8672904
113 + 8672791 = 8672904
131 + 8672773 = 8672904

Showing the first eight; more decompositions exist.
