Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594100, here are decompositions:

3 + 31594097 = 31594100
19 + 31594081 = 31594100
37 + 31594063 = 31594100
61 + 31594039 = 31594100
157 + 31593943 = 31594100
163 + 31593937 = 31594100
199 + 31593901 = 31594100
313 + 31593787 = 31594100

Showing the first eight; more decompositions exist.
