Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522498, here are decompositions:

5 + 31522493 = 31522498
47 + 31522451 = 31522498
167 + 31522331 = 31522498
251 + 31522247 = 31522498
257 + 31522241 = 31522498
269 + 31522229 = 31522498
317 + 31522181 = 31522498
479 + 31522019 = 31522498

Showing the first eight; more decompositions exist.
