Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89040, here are decompositions:

19 + 89021 = 89040
23 + 89017 = 89040
31 + 89009 = 89040
37 + 89003 = 89040
43 + 88997 = 89040
47 + 88993 = 89040
71 + 88969 = 89040
89 + 88951 = 89040

Showing the first eight; more decompositions exist.
