Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593408, here are decompositions:

17 + 31593391 = 31593408
19 + 31593389 = 31593408
31 + 31593377 = 31593408
101 + 31593307 = 31593408
109 + 31593299 = 31593408
157 + 31593251 = 31593408
211 + 31593197 = 31593408
311 + 31593097 = 31593408

Showing the first eight; more decompositions exist.
