Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31509022, here are decompositions:

5 + 31509017 = 31509022
23 + 31508999 = 31509022
101 + 31508921 = 31509022
179 + 31508843 = 31509022
383 + 31508639 = 31509022
401 + 31508621 = 31509022
443 + 31508579 = 31509022
569 + 31508453 = 31509022

Showing the first eight; more decompositions exist.
