Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31282, here are decompositions:

5 + 31277 = 31282
11 + 31271 = 31282
23 + 31259 = 31282
29 + 31253 = 31282
59 + 31223 = 31282
89 + 31193 = 31282
101 + 31181 = 31282
131 + 31151 = 31282

Showing the first eight; more decompositions exist.
