Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522918, here are decompositions:

17 + 31522901 = 31522918
29 + 31522889 = 31522918
71 + 31522847 = 31522918
389 + 31522529 = 31522918
467 + 31522451 = 31522918
587 + 31522331 = 31522918
641 + 31522277 = 31522918
677 + 31522241 = 31522918

Showing the first eight; more decompositions exist.
