Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538404, here are decompositions:

5 + 538399 = 538404
7 + 538397 = 538404
37 + 538367 = 538404
47 + 538357 = 538404
71 + 538333 = 538404
73 + 538331 = 538404
101 + 538303 = 538404
103 + 538301 = 538404

Showing the first eight; more decompositions exist.
