Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999616, here are decompositions:

3 + 999613 = 999616
5 + 999611 = 999616
17 + 999599 = 999616
53 + 999563 = 999616
179 + 999437 = 999616
227 + 999389 = 999616
239 + 999377 = 999616
257 + 999359 = 999616

Showing the first eight; more decompositions exist.
