Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31592304, here are decompositions:

13 + 31592291 = 31592304
47 + 31592257 = 31592304
101 + 31592203 = 31592304
131 + 31592173 = 31592304
181 + 31592123 = 31592304
251 + 31592053 = 31592304
257 + 31592047 = 31592304
307 + 31591997 = 31592304

Showing the first eight; more decompositions exist.
