Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593384, here are decompositions:

7 + 31593377 = 31593384
41 + 31593343 = 31593384
71 + 31593313 = 31593384
131 + 31593253 = 31593384
191 + 31593193 = 31593384
211 + 31593173 = 31593384
337 + 31593047 = 31593384
353 + 31593031 = 31593384

Showing the first eight; more decompositions exist.
