Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 27458, here are decompositions:

31 + 27427 = 27458
61 + 27397 = 27458
97 + 27361 = 27458
181 + 27277 = 27458
199 + 27259 = 27458
331 + 27127 = 27458
349 + 27109 = 27458
367 + 27091 = 27458

Showing the first eight; more decompositions exist.
