Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 36440, here are decompositions:

7 + 36433 = 36440
67 + 36373 = 36440
97 + 36343 = 36440
127 + 36313 = 36440
163 + 36277 = 36440
199 + 36241 = 36440
211 + 36229 = 36440
223 + 36217 = 36440

Showing the first eight; more decompositions exist.
