Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 20372, here are decompositions:

3 + 20369 = 20372
13 + 20359 = 20372
19 + 20353 = 20372
31 + 20341 = 20372
103 + 20269 = 20372
139 + 20233 = 20372
199 + 20173 = 20372
211 + 20161 = 20372

Showing the first eight; more decompositions exist.
