Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593944, here are decompositions:

7 + 31593937 = 31593944
13 + 31593931 = 31593944
43 + 31593901 = 31593944
157 + 31593787 = 31593944
181 + 31593763 = 31593944
223 + 31593721 = 31593944
241 + 31593703 = 31593944
313 + 31593631 = 31593944

Showing the first eight; more decompositions exist.
