Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31482522, here are decompositions:

11 + 31482511 = 31482522
13 + 31482509 = 31482522
23 + 31482499 = 31482522
83 + 31482439 = 31482522
173 + 31482349 = 31482522
179 + 31482343 = 31482522
229 + 31482293 = 31482522
241 + 31482281 = 31482522

Showing the first eight; more decompositions exist.
