Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625372, here are decompositions:

13 + 8625359 = 8625372
23 + 8625349 = 8625372
29 + 8625343 = 8625372
59 + 8625313 = 8625372
61 + 8625311 = 8625372
71 + 8625301 = 8625372
83 + 8625289 = 8625372
109 + 8625263 = 8625372

Showing the first eight; more decompositions exist.
