Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625644, here are decompositions:

3 + 8625641 = 8625644
7 + 8625637 = 8625644
103 + 8625541 = 8625644
127 + 8625517 = 8625644
151 + 8625493 = 8625644
193 + 8625451 = 8625644
331 + 8625313 = 8625644
397 + 8625247 = 8625644

Showing the first eight; more decompositions exist.
