Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625072, here are decompositions:

13 + 8625059 = 8625072
19 + 8625053 = 8625072
59 + 8625013 = 8625072
61 + 8625011 = 8625072
73 + 8624999 = 8625072
151 + 8624921 = 8625072
191 + 8624881 = 8625072
199 + 8624873 = 8625072

Showing the first eight; more decompositions exist.
