Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494, here are decompositions:

5 + 31489 = 31494
13 + 31481 = 31494
17 + 31477 = 31494
97 + 31397 = 31494
101 + 31393 = 31494
103 + 31391 = 31494
107 + 31387 = 31494
137 + 31357 = 31494

Showing the first eight; more decompositions exist.
