Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593346, here are decompositions:

3 + 31593343 = 31593346
47 + 31593299 = 31593346
149 + 31593197 = 31593346
173 + 31593173 = 31593346
353 + 31592993 = 31593346
503 + 31592843 = 31593346
599 + 31592747 = 31593346
683 + 31592663 = 31593346

Showing the first eight; more decompositions exist.
