Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31502458, here are decompositions:

17 + 31502441 = 31502458
179 + 31502279 = 31502458
269 + 31502189 = 31502458
311 + 31502147 = 31502458
359 + 31502099 = 31502458
479 + 31501979 = 31502458
521 + 31501937 = 31502458
677 + 31501781 = 31502458

Showing the first eight; more decompositions exist.
