Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8653666, here are decompositions:

53 + 8653613 = 8653666
113 + 8653553 = 8653666
137 + 8653529 = 8653666
149 + 8653517 = 8653666
179 + 8653487 = 8653666
293 + 8653373 = 8653666
347 + 8653319 = 8653666
383 + 8653283 = 8653666

Showing the first eight; more decompositions exist.
