Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31594138, here are decompositions:

5 + 31594133 = 31594138
41 + 31594097 = 31594138
89 + 31594049 = 31594138
179 + 31593959 = 31594138
269 + 31593869 = 31594138
419 + 31593719 = 31594138
449 + 31593689 = 31594138
491 + 31593647 = 31594138

Showing the first eight; more decompositions exist.
