Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625524, here are decompositions:

3 + 8625521 = 8625524
7 + 8625517 = 8625524
31 + 8625493 = 8625524
73 + 8625451 = 8625524
181 + 8625343 = 8625524
211 + 8625313 = 8625524
223 + 8625301 = 8625524
277 + 8625247 = 8625524

Showing the first eight; more decompositions exist.
