Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522620, here are decompositions:

7 + 31522613 = 31522620
23 + 31522597 = 31522620
29 + 31522591 = 31522620
37 + 31522583 = 31522620
67 + 31522553 = 31522620
71 + 31522549 = 31522620
79 + 31522541 = 31522620
97 + 31522523 = 31522620

Showing the first eight; more decompositions exist.
