Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522522, here are decompositions:

29 + 31522493 = 31522522
71 + 31522451 = 31522522
89 + 31522433 = 31522522
149 + 31522373 = 31522522
191 + 31522331 = 31522522
281 + 31522241 = 31522522
293 + 31522229 = 31522522
419 + 31522103 = 31522522

Showing the first eight; more decompositions exist.
