Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522798, here are decompositions:

257 + 31522541 = 31522798
269 + 31522529 = 31522798
347 + 31522451 = 31522798
467 + 31522331 = 31522798
521 + 31522277 = 31522798
557 + 31522241 = 31522798
569 + 31522229 = 31522798
617 + 31522181 = 31522798

Showing the first eight; more decompositions exist.
