Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538828, here are decompositions:

5 + 538823 = 538828
11 + 538817 = 538828
29 + 538799 = 538828
89 + 538739 = 538828
107 + 538721 = 538828
131 + 538697 = 538828
179 + 538649 = 538828
239 + 538589 = 538828

Showing the first eight; more decompositions exist.
