Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592340, here are decompositions:

29 + 31592311 = 31592340
83 + 31592257 = 31592340
127 + 31592213 = 31592340
137 + 31592203 = 31592340
167 + 31592173 = 31592340
179 + 31592161 = 31592340
181 + 31592159 = 31592340
191 + 31592149 = 31592340

Showing the first eight; more decompositions exist.
