Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672148, here are decompositions:

31 + 8672117 = 8672148
47 + 8672101 = 8672148
61 + 8672087 = 8672148
101 + 8672047 = 8672148
157 + 8671991 = 8672148
167 + 8671981 = 8672148
181 + 8671967 = 8672148
211 + 8671937 = 8672148

Showing the first eight; more decompositions exist.
