Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625178, here are decompositions:

5 + 8625173 = 8625178
47 + 8625131 = 8625178
59 + 8625119 = 8625178
101 + 8625077 = 8625178
167 + 8625011 = 8625178
179 + 8624999 = 8625178
197 + 8624981 = 8625178
257 + 8624921 = 8625178

Showing the first eight; more decompositions exist.
