Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522548, here are decompositions:

7 + 31522541 = 31522548
19 + 31522529 = 31522548
89 + 31522459 = 31522548
97 + 31522451 = 31522548
107 + 31522441 = 31522548
137 + 31522411 = 31522548
191 + 31522357 = 31522548
251 + 31522297 = 31522548

Showing the first eight; more decompositions exist.
