Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8625172, here are decompositions:

41 + 8625131 = 8625172
53 + 8625119 = 8625172
89 + 8625083 = 8625172
113 + 8625059 = 8625172
173 + 8624999 = 8625172
191 + 8624981 = 8625172
251 + 8624921 = 8625172
401 + 8624771 = 8625172

Showing the first eight; more decompositions exist.
