Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523582, here are decompositions:

5 + 523577 = 523582
11 + 523571 = 523582
29 + 523553 = 523582
41 + 523541 = 523582
71 + 523511 = 523582
89 + 523493 = 523582
149 + 523433 = 523582
179 + 523403 = 523582

Showing the first eight; more decompositions exist.
