Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573734, here are decompositions:

37 + 31573697 = 31573734
107 + 31573627 = 31573734
113 + 31573621 = 31573734
151 + 31573583 = 31573734
163 + 31573571 = 31573734
173 + 31573561 = 31573734
211 + 31573523 = 31573734
233 + 31573501 = 31573734

Showing the first eight; more decompositions exist.
