Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8646378, here are decompositions:

17 + 8646361 = 8646378
61 + 8646317 = 8646378
79 + 8646299 = 8646378
101 + 8646277 = 8646378
109 + 8646269 = 8646378
131 + 8646247 = 8646378
151 + 8646227 = 8646378
157 + 8646221 = 8646378

Showing the first eight; more decompositions exist.
