Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653372, here are decompositions:

11 + 8653361 = 8653372
29 + 8653343 = 8653372
53 + 8653319 = 8653372
89 + 8653283 = 8653372
113 + 8653259 = 8653372
131 + 8653241 = 8653372
173 + 8653199 = 8653372
251 + 8653121 = 8653372

Showing the first eight; more decompositions exist.
