Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538842, here are decompositions:

13 + 538829 = 538842
19 + 538823 = 538842
41 + 538801 = 538842
43 + 538799 = 538842
53 + 538789 = 538842
71 + 538771 = 538842
79 + 538763 = 538842
103 + 538739 = 538842

Showing the first eight; more decompositions exist.
