Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592172, here are decompositions:

11 + 31592161 = 31592172
13 + 31592159 = 31592172
23 + 31592149 = 31592172
43 + 31592129 = 31592172
173 + 31591999 = 31592172
179 + 31591993 = 31592172
193 + 31591979 = 31592172
263 + 31591909 = 31592172

Showing the first eight; more decompositions exist.
