Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592358, here are decompositions:

11 + 31592347 = 31592358
47 + 31592311 = 31592358
67 + 31592291 = 31592358
101 + 31592257 = 31592358
139 + 31592219 = 31592358
197 + 31592161 = 31592358
199 + 31592159 = 31592358
229 + 31592129 = 31592358

Showing the first eight; more decompositions exist.
