Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999568, here are decompositions:

5 + 999563 = 999568
47 + 999521 = 999568
131 + 999437 = 999568
137 + 999431 = 999568
179 + 999389 = 999568
191 + 999377 = 999568
197 + 999371 = 999568
239 + 999329 = 999568

Showing the first eight; more decompositions exist.
