Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577056, here are decompositions:

3 + 31577053 = 31577056
47 + 31577009 = 31577056
89 + 31576967 = 31577056
107 + 31576949 = 31577056
167 + 31576889 = 31577056
317 + 31576739 = 31577056
347 + 31576709 = 31577056
353 + 31576703 = 31577056

Showing the first eight; more decompositions exist.
