Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625444, here are decompositions:

13 + 8625431 = 8625444
101 + 8625343 = 8625444
127 + 8625317 = 8625444
131 + 8625313 = 8625444
181 + 8625263 = 8625444
197 + 8625247 = 8625444
211 + 8625233 = 8625444
241 + 8625203 = 8625444

Showing the first eight; more decompositions exist.
