Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522938, here are decompositions:

37 + 31522901 = 31522938
191 + 31522747 = 31522938
269 + 31522669 = 31522938
281 + 31522657 = 31522938
347 + 31522591 = 31522938
389 + 31522549 = 31522938
397 + 31522541 = 31522938
409 + 31522529 = 31522938

Showing the first eight; more decompositions exist.
