Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625530, here are decompositions:

3 + 8625527 = 8625530
13 + 8625517 = 8625530
37 + 8625493 = 8625530
79 + 8625451 = 8625530
181 + 8625349 = 8625530
229 + 8625301 = 8625530
241 + 8625289 = 8625530
283 + 8625247 = 8625530

Showing the first eight; more decompositions exist.
