Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 999582, here are decompositions:

19 + 999563 = 999582
29 + 999553 = 999582
41 + 999541 = 999582
53 + 999529 = 999582
61 + 999521 = 999582
83 + 999499 = 999582
131 + 999451 = 999582
149 + 999433 = 999582

Showing the first eight; more decompositions exist.
