Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573196, here are decompositions:

7 + 31573189 = 31573196
43 + 31573153 = 31573196
73 + 31573123 = 31573196
103 + 31573093 = 31573196
139 + 31573057 = 31573196
373 + 31572823 = 31573196
433 + 31572763 = 31573196
463 + 31572733 = 31573196

Showing the first eight; more decompositions exist.
