Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576, here are decompositions:

3 + 31573 = 31576
29 + 31547 = 31576
59 + 31517 = 31576
107 + 31469 = 31576
179 + 31397 = 31576
197 + 31379 = 31576
239 + 31337 = 31576
257 + 31319 = 31576

Showing the first eight; more decompositions exist.
