Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1001582, here are decompositions:

13 + 1001569 = 1001582
19 + 1001563 = 1001582
31 + 1001551 = 1001582
151 + 1001431 = 1001582
181 + 1001401 = 1001582
193 + 1001389 = 1001582
229 + 1001353 = 1001582
271 + 1001311 = 1001582

Showing the first eight; more decompositions exist.
