Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672140, here are decompositions:

23 + 8672117 = 8672140
41 + 8672099 = 8672140
53 + 8672087 = 8672140
137 + 8672003 = 8672140
149 + 8671991 = 8672140
173 + 8671967 = 8672140
233 + 8671907 = 8672140
401 + 8671739 = 8672140

Showing the first eight; more decompositions exist.
