Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625492, here are decompositions:

13 + 8625479 = 8625492
41 + 8625451 = 8625492
61 + 8625431 = 8625492
149 + 8625343 = 8625492
179 + 8625313 = 8625492
181 + 8625311 = 8625492
191 + 8625301 = 8625492
229 + 8625263 = 8625492

Showing the first eight; more decompositions exist.
