Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522958, here are decompositions:

7 + 31522951 = 31522958
211 + 31522747 = 31522958
241 + 31522717 = 31522958
367 + 31522591 = 31522958
409 + 31522549 = 31522958
499 + 31522459 = 31522958
547 + 31522411 = 31522958
601 + 31522357 = 31522958

Showing the first eight; more decompositions exist.
