Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673138, here are decompositions:

7 + 8673131 = 8673138
11 + 8673127 = 8673138
17 + 8673121 = 8673138
29 + 8673109 = 8673138
31 + 8673107 = 8673138
41 + 8673097 = 8673138
101 + 8673037 = 8673138
109 + 8673029 = 8673138

Showing the first eight; more decompositions exist.
