Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31492, here are decompositions:

3 + 31489 = 31492
11 + 31481 = 31492
23 + 31469 = 31492
101 + 31391 = 31492
113 + 31379 = 31492
173 + 31319 = 31492
233 + 31259 = 31492
239 + 31253 = 31492

Showing the first eight; more decompositions exist.
