Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594008, here are decompositions:

71 + 31593937 = 31594008
107 + 31593901 = 31594008
139 + 31593869 = 31594008
211 + 31593797 = 31594008
241 + 31593767 = 31594008
367 + 31593641 = 31594008
379 + 31593629 = 31594008
401 + 31593607 = 31594008

Showing the first eight; more decompositions exist.
