Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005588, here are decompositions:

7 + 1005581 = 1005588
37 + 1005551 = 1005588
47 + 1005541 = 1005588
61 + 1005527 = 1005588
107 + 1005481 = 1005588
131 + 1005457 = 1005588
149 + 1005439 = 1005588
151 + 1005437 = 1005588

Showing the first eight; more decompositions exist.
