Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538836, here are decompositions:

7 + 538829 = 538836
13 + 538823 = 538836
19 + 538817 = 538836
37 + 538799 = 538836
47 + 538789 = 538836
59 + 538777 = 538836
73 + 538763 = 538836
97 + 538739 = 538836

Showing the first eight; more decompositions exist.
