Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 57040, here are decompositions:

3 + 57037 = 57040
41 + 56999 = 57040
47 + 56993 = 57040
83 + 56957 = 57040
89 + 56951 = 57040
131 + 56909 = 57040
149 + 56891 = 57040
167 + 56873 = 57040

Showing the first eight; more decompositions exist.
