Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57440, here are decompositions:

13 + 57427 = 57440
43 + 57397 = 57440
67 + 57373 = 57440
73 + 57367 = 57440
109 + 57331 = 57440
139 + 57301 = 57440
157 + 57283 = 57440
181 + 57259 = 57440

Showing the first eight; more decompositions exist.
