Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31296, here are decompositions:

19 + 31277 = 31296
29 + 31267 = 31296
37 + 31259 = 31296
43 + 31253 = 31296
47 + 31249 = 31296
59 + 31237 = 31296
73 + 31223 = 31296
103 + 31193 = 31296

Showing the first eight; more decompositions exist.
