Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592308, here are decompositions:

17 + 31592291 = 31592308
89 + 31592219 = 31592308
149 + 31592159 = 31592308
179 + 31592129 = 31592308
257 + 31592051 = 31592308
269 + 31592039 = 31592308
311 + 31591997 = 31592308
557 + 31591751 = 31592308

Showing the first eight; more decompositions exist.
