Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573716, here are decompositions:

19 + 31573697 = 31573716
37 + 31573679 = 31573716
73 + 31573643 = 31573716
89 + 31573627 = 31573716
157 + 31573559 = 31573716
193 + 31573523 = 31573716
353 + 31573363 = 31573716
359 + 31573357 = 31573716

Showing the first eight; more decompositions exist.
