Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672146, here are decompositions:

29 + 8672117 = 8672146
47 + 8672099 = 8672146
59 + 8672087 = 8672146
83 + 8672063 = 8672146
167 + 8671979 = 8672146
179 + 8671967 = 8672146
227 + 8671919 = 8672146
239 + 8671907 = 8672146

Showing the first eight; more decompositions exist.
