Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 493844, here are decompositions:

31 + 493813 = 493844
37 + 493807 = 493844
67 + 493777 = 493844
97 + 493747 = 493844
151 + 493693 = 493844
223 + 493621 = 493844
271 + 493573 = 493844
277 + 493567 = 493844

Showing the first eight; more decompositions exist.
