Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8747178, here are decompositions:

7 + 8747171 = 8747178
19 + 8747159 = 8747178
59 + 8747119 = 8747178
67 + 8747111 = 8747178
107 + 8747071 = 8747178
137 + 8747041 = 8747178
179 + 8746999 = 8747178
199 + 8746979 = 8747178

Showing the first eight; more decompositions exist.
