Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40256, here are decompositions:

3 + 40253 = 40256
19 + 40237 = 40256
43 + 40213 = 40256
67 + 40189 = 40256
79 + 40177 = 40256
103 + 40153 = 40256
127 + 40129 = 40256
157 + 40099 = 40256

Showing the first eight; more decompositions exist.
