Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538944, here are decompositions:

5 + 538939 = 538944
13 + 538931 = 538944
17 + 538927 = 538944
23 + 538921 = 538944
67 + 538877 = 538944
73 + 538871 = 538944
103 + 538841 = 538944
127 + 538817 = 538944

Showing the first eight; more decompositions exist.
