Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582824, here are decompositions:

5 + 31582819 = 31582824
43 + 31582781 = 31582824
47 + 31582777 = 31582824
67 + 31582757 = 31582824
151 + 31582673 = 31582824
157 + 31582667 = 31582824
191 + 31582633 = 31582824
193 + 31582631 = 31582824

Showing the first eight; more decompositions exist.
