Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573016, here are decompositions:

37 + 31572979 = 31573016
67 + 31572949 = 31573016
73 + 31572943 = 31573016
193 + 31572823 = 31573016
283 + 31572733 = 31573016
367 + 31572649 = 31573016
379 + 31572637 = 31573016
457 + 31572559 = 31573016

Showing the first eight; more decompositions exist.
