Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625130, here are decompositions:

11 + 8625119 = 8625130
47 + 8625083 = 8625130
53 + 8625077 = 8625130
71 + 8625059 = 8625130
131 + 8624999 = 8625130
149 + 8624981 = 8625130
257 + 8624873 = 8625130
359 + 8624771 = 8625130

Showing the first eight; more decompositions exist.
