Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673158, here are decompositions:

31 + 8673127 = 8673158
37 + 8673121 = 8673158
61 + 8673097 = 8673158
139 + 8673019 = 8673158
211 + 8672947 = 8673158
337 + 8672821 = 8673158
367 + 8672791 = 8673158
379 + 8672779 = 8673158

Showing the first eight; more decompositions exist.
