Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593184, here are decompositions:

11 + 31593173 = 31593184
137 + 31593047 = 31593184
173 + 31593011 = 31593184
191 + 31592993 = 31593184
263 + 31592921 = 31593184
521 + 31592663 = 31593184
563 + 31592621 = 31593184
617 + 31592567 = 31593184

Showing the first eight; more decompositions exist.
