Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57438, here are decompositions:

11 + 57427 = 57438
41 + 57397 = 57438
71 + 57367 = 57438
89 + 57349 = 57438
107 + 57331 = 57438
109 + 57329 = 57438
137 + 57301 = 57438
151 + 57287 = 57438

Showing the first eight; more decompositions exist.
