Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593258, here are decompositions:

5 + 31593253 = 31593258
7 + 31593251 = 31593258
61 + 31593197 = 31593258
149 + 31593109 = 31593258
211 + 31593047 = 31593258
227 + 31593031 = 31593258
311 + 31592947 = 31593258
337 + 31592921 = 31593258

Showing the first eight; more decompositions exist.
