Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8640174, here are decompositions:

5 + 8640169 = 8640174
13 + 8640161 = 8640174
41 + 8640133 = 8640174
157 + 8640017 = 8640174
173 + 8640001 = 8640174
197 + 8639977 = 8640174
223 + 8639951 = 8640174
251 + 8639923 = 8640174

Showing the first eight; more decompositions exist.
