Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573514, here are decompositions:

13 + 31573501 = 31573514
151 + 31573363 = 31573514
157 + 31573357 = 31573514
421 + 31573093 = 31573514
457 + 31573057 = 31573514
487 + 31573027 = 31573514
571 + 31572943 = 31573514
613 + 31572901 = 31573514

Showing the first eight; more decompositions exist.
