Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999566, here are decompositions:

3 + 999563 = 999566
13 + 999553 = 999566
37 + 999529 = 999566
67 + 999499 = 999566
349 + 999217 = 999566
367 + 999199 = 999566
397 + 999169 = 999566
433 + 999133 = 999566

Showing the first eight; more decompositions exist.
