Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10240, here are decompositions:

17 + 10223 = 10240
29 + 10211 = 10240
47 + 10193 = 10240
59 + 10181 = 10240
71 + 10169 = 10240
89 + 10151 = 10240
101 + 10139 = 10240
107 + 10133 = 10240

Showing the first eight; more decompositions exist.
