Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57458, here are decompositions:

31 + 57427 = 57458
61 + 57397 = 57458
109 + 57349 = 57458
127 + 57331 = 57458
157 + 57301 = 57458
199 + 57259 = 57458
421 + 57037 = 57458
547 + 56911 = 57458

Showing the first eight; more decompositions exist.
