Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538900, here are decompositions:

23 + 538877 = 538900
29 + 538871 = 538900
59 + 538841 = 538900
71 + 538829 = 538900
83 + 538817 = 538900
101 + 538799 = 538900
137 + 538763 = 538900
149 + 538751 = 538900

Showing the first eight; more decompositions exist.
