Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625268, here are decompositions:

5 + 8625263 = 8625268
137 + 8625131 = 8625268
149 + 8625119 = 8625268
191 + 8625077 = 8625268
257 + 8625011 = 8625268
269 + 8624999 = 8625268
347 + 8624921 = 8625268
461 + 8624807 = 8625268

Showing the first eight; more decompositions exist.
