Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673178, here are decompositions:

11 + 8673167 = 8673178
47 + 8673131 = 8673178
71 + 8673107 = 8673178
149 + 8673029 = 8673178
167 + 8673011 = 8673178
251 + 8672927 = 8673178
281 + 8672897 = 8673178
317 + 8672861 = 8673178

Showing the first eight; more decompositions exist.
