Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538958, here are decompositions:

19 + 538939 = 538958
31 + 538927 = 538958
37 + 538921 = 538958
157 + 538801 = 538958
181 + 538777 = 538958
307 + 538651 = 538958
337 + 538621 = 538958
379 + 538579 = 538958

Showing the first eight; more decompositions exist.
