Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533522, here are decompositions:

5 + 31533517 = 31533522
11 + 31533511 = 31533522
23 + 31533499 = 31533522
61 + 31533461 = 31533522
71 + 31533451 = 31533522
73 + 31533449 = 31533522
109 + 31533413 = 31533522
113 + 31533409 = 31533522

Showing the first eight; more decompositions exist.
