Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538548, here are decompositions:

19 + 538529 = 538548
29 + 538519 = 538548
37 + 538511 = 538548
61 + 538487 = 538548
67 + 538481 = 538548
137 + 538411 = 538548
149 + 538399 = 538548
151 + 538397 = 538548

Showing the first eight; more decompositions exist.
