Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592328, here are decompositions:

17 + 31592311 = 31592328
37 + 31592291 = 31592328
71 + 31592257 = 31592328
109 + 31592219 = 31592328
167 + 31592161 = 31592328
179 + 31592149 = 31592328
199 + 31592129 = 31592328
277 + 31592051 = 31592328

Showing the first eight; more decompositions exist.
