Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672130, here are decompositions:

13 + 8672117 = 8672130
29 + 8672101 = 8672130
31 + 8672099 = 8672130
43 + 8672087 = 8672130
67 + 8672063 = 8672130
83 + 8672047 = 8672130
127 + 8672003 = 8672130
139 + 8671991 = 8672130

Showing the first eight; more decompositions exist.
