Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593202, here are decompositions:

5 + 31593197 = 31593202
29 + 31593173 = 31593202
191 + 31593011 = 31593202
281 + 31592921 = 31593202
353 + 31592849 = 31593202
359 + 31592843 = 31593202
911 + 31592291 = 31593202
983 + 31592219 = 31593202

Showing the first eight; more decompositions exist.
