Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522928, here are decompositions:

181 + 31522747 = 31522928
211 + 31522717 = 31522928
271 + 31522657 = 31522928
331 + 31522597 = 31522928
337 + 31522591 = 31522928
379 + 31522549 = 31522928
487 + 31522441 = 31522928
571 + 31522357 = 31522928

Showing the first eight; more decompositions exist.
