Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999560, here are decompositions:

7 + 999553 = 999560
19 + 999541 = 999560
31 + 999529 = 999560
61 + 999499 = 999560
109 + 999451 = 999560
127 + 999433 = 999560
229 + 999331 = 999560
379 + 999181 = 999560

Showing the first eight; more decompositions exist.
