Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31576534, here are decompositions:

5 + 31576529 = 31576534
23 + 31576511 = 31576534
107 + 31576427 = 31576534
131 + 31576403 = 31576534
167 + 31576367 = 31576534
251 + 31576283 = 31576534
281 + 31576253 = 31576534
293 + 31576241 = 31576534

Showing the first eight; more decompositions exist.
