Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593800, here are decompositions:

3 + 31593797 = 31593800
13 + 31593787 = 31593800
37 + 31593763 = 31593800
79 + 31593721 = 31593800
97 + 31593703 = 31593800
157 + 31593643 = 31593800
193 + 31593607 = 31593800
211 + 31593589 = 31593800

Showing the first eight; more decompositions exist.
