Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31593140, here are decompositions:

31 + 31593109 = 31593140
43 + 31593097 = 31593140
109 + 31593031 = 31593140
157 + 31592983 = 31593140
181 + 31592959 = 31593140
193 + 31592947 = 31593140
307 + 31592833 = 31593140
331 + 31592809 = 31593140

Showing the first eight; more decompositions exist.
