Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31591354, here are decompositions:

5 + 31591349 = 31591354
17 + 31591337 = 31591354
23 + 31591331 = 31591354
167 + 31591187 = 31591354
293 + 31591061 = 31591354
317 + 31591037 = 31591354
461 + 31590893 = 31591354
467 + 31590887 = 31591354

Showing the first eight; more decompositions exist.
