Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673156, here are decompositions:

29 + 8673127 = 8673156
43 + 8673113 = 8673156
47 + 8673109 = 8673156
59 + 8673097 = 8673156
83 + 8673073 = 8673156
127 + 8673029 = 8673156
137 + 8673019 = 8673156
223 + 8672933 = 8673156

Showing the first eight; more decompositions exist.
