Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001588, here are decompositions:

19 + 1001569 = 1001588
37 + 1001551 = 1001588
61 + 1001527 = 1001588
97 + 1001491 = 1001588
157 + 1001431 = 1001588
199 + 1001389 = 1001588
241 + 1001347 = 1001588
277 + 1001311 = 1001588

Showing the first eight; more decompositions exist.
