Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672128, here are decompositions:

11 + 8672117 = 8672128
29 + 8672099 = 8672128
41 + 8672087 = 8672128
137 + 8671991 = 8672128
149 + 8671979 = 8672128
191 + 8671937 = 8672128
317 + 8671811 = 8672128
359 + 8671769 = 8672128

Showing the first eight; more decompositions exist.
