Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8738178, here are decompositions:

17 + 8738161 = 8738178
89 + 8738089 = 8738178
107 + 8738071 = 8738178
131 + 8738047 = 8738178
167 + 8738011 = 8738178
199 + 8737979 = 8738178
257 + 8737921 = 8738178
307 + 8737871 = 8738178

Showing the first eight; more decompositions exist.
