Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573794, here are decompositions:

37 + 31573757 = 31573794
41 + 31573753 = 31573794
47 + 31573747 = 31573794
97 + 31573697 = 31573794
151 + 31573643 = 31573794
167 + 31573627 = 31573794
173 + 31573621 = 31573794
211 + 31573583 = 31573794

Showing the first eight; more decompositions exist.
