Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673378, here are decompositions:

5 + 8673373 = 8673378
17 + 8673361 = 8673378
19 + 8673359 = 8673378
31 + 8673347 = 8673378
37 + 8673341 = 8673378
107 + 8673271 = 8673378
157 + 8673221 = 8673378
179 + 8673199 = 8673378

Showing the first eight; more decompositions exist.
