Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538744, here are decompositions:

5 + 538739 = 538744
23 + 538721 = 538744
47 + 538697 = 538744
191 + 538553 = 538744
233 + 538511 = 538744
257 + 538487 = 538744
263 + 538481 = 538744
347 + 538397 = 538744

Showing the first eight; more decompositions exist.
