Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593318, here are decompositions:

5 + 31593313 = 31593318
11 + 31593307 = 31593318
19 + 31593299 = 31593318
67 + 31593251 = 31593318
271 + 31593047 = 31593318
307 + 31593011 = 31593318
347 + 31592971 = 31593318
359 + 31592959 = 31593318

Showing the first eight; more decompositions exist.
