Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592360, here are decompositions:

3 + 31592357 = 31592360
13 + 31592347 = 31592360
103 + 31592257 = 31592360
157 + 31592203 = 31592360
199 + 31592161 = 31592360
211 + 31592149 = 31592360
307 + 31592053 = 31592360
313 + 31592047 = 31592360

Showing the first eight; more decompositions exist.
