Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534, here are decompositions:

3 + 31531 = 31534
17 + 31517 = 31534
23 + 31511 = 31534
53 + 31481 = 31534
137 + 31397 = 31534
197 + 31337 = 31534
227 + 31307 = 31534
257 + 31277 = 31534

Showing the first eight; more decompositions exist.
