Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576732, here are decompositions:

23 + 31576709 = 31576732
29 + 31576703 = 31576732
59 + 31576673 = 31576732
113 + 31576619 = 31576732
149 + 31576583 = 31576732
191 + 31576541 = 31576732
293 + 31576439 = 31576732
359 + 31576373 = 31576732

Showing the first eight; more decompositions exist.
