Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40456, here are decompositions:

23 + 40433 = 40456
29 + 40427 = 40456
113 + 40343 = 40456
167 + 40289 = 40456
173 + 40283 = 40456
179 + 40277 = 40456
263 + 40193 = 40456
293 + 40163 = 40456

Showing the first eight; more decompositions exist.
