Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672158, here are decompositions:

41 + 8672117 = 8672158
59 + 8672099 = 8672158
71 + 8672087 = 8672158
167 + 8671991 = 8672158
179 + 8671979 = 8672158
191 + 8671967 = 8672158
239 + 8671919 = 8672158
251 + 8671907 = 8672158

Showing the first eight; more decompositions exist.
