Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8616178, here are decompositions:

5 + 8616173 = 8616178
29 + 8616149 = 8616178
47 + 8616131 = 8616178
89 + 8616089 = 8616178
107 + 8616071 = 8616178
149 + 8616029 = 8616178
167 + 8616011 = 8616178
521 + 8615657 = 8616178

Showing the first eight; more decompositions exist.
