Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31402, here are decompositions:

5 + 31397 = 31402
11 + 31391 = 31402
23 + 31379 = 31402
83 + 31319 = 31402
131 + 31271 = 31402
149 + 31253 = 31402
179 + 31223 = 31402
251 + 31151 = 31402

Showing the first eight; more decompositions exist.
