Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593954, here are decompositions:

11 + 31593943 = 31593954
17 + 31593937 = 31593954
23 + 31593931 = 31593954
53 + 31593901 = 31593954
157 + 31593797 = 31593954
167 + 31593787 = 31593954
191 + 31593763 = 31593954
233 + 31593721 = 31593954

Showing the first eight; more decompositions exist.
