Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31582958, here are decompositions:

7 + 31582951 = 31582958
61 + 31582897 = 31582958
67 + 31582891 = 31582958
139 + 31582819 = 31582958
181 + 31582777 = 31582958
229 + 31582729 = 31582958
331 + 31582627 = 31582958
349 + 31582609 = 31582958

Showing the first eight; more decompositions exist.
