Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625438, here are decompositions:

7 + 8625431 = 8625438
79 + 8625359 = 8625438
89 + 8625349 = 8625438
127 + 8625311 = 8625438
137 + 8625301 = 8625438
149 + 8625289 = 8625438
191 + 8625247 = 8625438
251 + 8625187 = 8625438

Showing the first eight; more decompositions exist.
