Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 40744, here are decompositions:

5 + 40739 = 40744
47 + 40697 = 40744
107 + 40637 = 40744
167 + 40577 = 40744
251 + 40493 = 40744
257 + 40487 = 40744
311 + 40433 = 40744
317 + 40427 = 40744

Showing the first eight; more decompositions exist.
