Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577032, here are decompositions:

23 + 31577009 = 31577032
41 + 31576991 = 31577032
83 + 31576949 = 31577032
101 + 31576931 = 31577032
131 + 31576901 = 31577032
281 + 31576751 = 31577032
293 + 31576739 = 31577032
359 + 31576673 = 31577032

Showing the first eight; more decompositions exist.
