Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672136, here are decompositions:

19 + 8672117 = 8672136
37 + 8672099 = 8672136
73 + 8672063 = 8672136
89 + 8672047 = 8672136
149 + 8671987 = 8672136
157 + 8671979 = 8672136
199 + 8671937 = 8672136
229 + 8671907 = 8672136

Showing the first eight; more decompositions exist.
