Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593912, here are decompositions:

11 + 31593901 = 31593912
43 + 31593869 = 31593912
73 + 31593839 = 31593912
79 + 31593833 = 31593912
149 + 31593763 = 31593912
191 + 31593721 = 31593912
193 + 31593719 = 31593912
223 + 31593689 = 31593912

Showing the first eight; more decompositions exist.
