Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594152, here are decompositions:

19 + 31594133 = 31594152
71 + 31594081 = 31594152
89 + 31594063 = 31594152
103 + 31594049 = 31594152
113 + 31594039 = 31594152
193 + 31593959 = 31594152
199 + 31593953 = 31594152
251 + 31593901 = 31594152

Showing the first eight; more decompositions exist.
