Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538872, here are decompositions:

31 + 538841 = 538872
43 + 538829 = 538872
71 + 538801 = 538872
73 + 538799 = 538872
83 + 538789 = 538872
101 + 538771 = 538872
109 + 538763 = 538872
149 + 538723 = 538872

Showing the first eight; more decompositions exist.
