Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31577008, here are decompositions:

17 + 31576991 = 31577008
41 + 31576967 = 31577008
59 + 31576949 = 31577008
107 + 31576901 = 31577008
257 + 31576751 = 31577008
269 + 31576739 = 31577008
389 + 31576619 = 31577008
467 + 31576541 = 31577008

Showing the first eight; more decompositions exist.
