Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670178, here are decompositions:

71 + 8670107 = 8670178
89 + 8670089 = 8670178
107 + 8670071 = 8670178
137 + 8670041 = 8670178
149 + 8670029 = 8670178
197 + 8669981 = 8670178
239 + 8669939 = 8670178
281 + 8669897 = 8670178

Showing the first eight; more decompositions exist.
