Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8693644, here are decompositions:

5 + 8693639 = 8693644
17 + 8693627 = 8693644
257 + 8693387 = 8693644
263 + 8693381 = 8693644
317 + 8693327 = 8693644
431 + 8693213 = 8693644
653 + 8692991 = 8693644
683 + 8692961 = 8693644

Showing the first eight; more decompositions exist.
