Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592208, here are decompositions:

5 + 31592203 = 31592208
47 + 31592161 = 31592208
59 + 31592149 = 31592208
79 + 31592129 = 31592208
157 + 31592051 = 31592208
211 + 31591997 = 31592208
229 + 31591979 = 31592208
251 + 31591957 = 31592208

Showing the first eight; more decompositions exist.
