Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672170, here are decompositions:

53 + 8672117 = 8672170
71 + 8672099 = 8672170
83 + 8672087 = 8672170
107 + 8672063 = 8672170
167 + 8672003 = 8672170
179 + 8671991 = 8672170
191 + 8671979 = 8672170
233 + 8671937 = 8672170

Showing the first eight; more decompositions exist.
