Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522558, here are decompositions:

5 + 31522553 = 31522558
17 + 31522541 = 31522558
29 + 31522529 = 31522558
107 + 31522451 = 31522558
227 + 31522331 = 31522558
281 + 31522277 = 31522558
311 + 31522247 = 31522558
317 + 31522241 = 31522558

Showing the first eight; more decompositions exist.
