Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31573752, here are decompositions:

5 + 31573747 = 31573752
73 + 31573679 = 31573752
109 + 31573643 = 31573752
113 + 31573639 = 31573752
131 + 31573621 = 31573752
181 + 31573571 = 31573752
191 + 31573561 = 31573752
193 + 31573559 = 31573752

Showing the first eight; more decompositions exist.
