Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577952, here are decompositions:

11 + 31577941 = 31577952
13 + 31577939 = 31577952
23 + 31577929 = 31577952
53 + 31577899 = 31577952
103 + 31577849 = 31577952
139 + 31577813 = 31577952
173 + 31577779 = 31577952
179 + 31577773 = 31577952

Showing the first eight; more decompositions exist.
