Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498, here are decompositions:

17 + 31481 = 31498
29 + 31469 = 31498
101 + 31397 = 31498
107 + 31391 = 31498
179 + 31319 = 31498
191 + 31307 = 31498
227 + 31271 = 31498
239 + 31259 = 31498

Showing the first eight; more decompositions exist.
