Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593394, here are decompositions:

3 + 31593391 = 31593394
5 + 31593389 = 31593394
17 + 31593377 = 31593394
197 + 31593197 = 31593394
347 + 31593047 = 31593394
383 + 31593011 = 31593394
401 + 31592993 = 31593394
647 + 31592747 = 31593394

Showing the first eight; more decompositions exist.
