Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 51458, here are decompositions:

19 + 51439 = 51458
31 + 51427 = 51458
37 + 51421 = 51458
97 + 51361 = 51458
109 + 51349 = 51458
151 + 51307 = 51458
229 + 51229 = 51458
241 + 51217 = 51458

Showing the first eight; more decompositions exist.
