Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482958, here are decompositions:

11 + 31482947 = 31482958
137 + 31482821 = 31482958
179 + 31482779 = 31482958
197 + 31482761 = 31482958
251 + 31482707 = 31482958
317 + 31482641 = 31482958
359 + 31482599 = 31482958
389 + 31482569 = 31482958

Showing the first eight; more decompositions exist.
