Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592384, here are decompositions:

7 + 31592377 = 31592384
37 + 31592347 = 31592384
73 + 31592311 = 31592384
127 + 31592257 = 31592384
181 + 31592203 = 31592384
211 + 31592173 = 31592384
223 + 31592161 = 31592384
331 + 31592053 = 31592384

Showing the first eight; more decompositions exist.
