Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673040, here are decompositions:

3 + 8673037 = 8673040
11 + 8673029 = 8673040
29 + 8673011 = 8673040
71 + 8672969 = 8673040
107 + 8672933 = 8673040
113 + 8672927 = 8673040
149 + 8672891 = 8673040
179 + 8672861 = 8673040

Showing the first eight; more decompositions exist.
