Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 538444, here are decompositions:

47 + 538397 = 538444
113 + 538331 = 538444
197 + 538247 = 538444
281 + 538163 = 538444
293 + 538151 = 538444
317 + 538127 = 538444
443 + 538001 = 538444
503 + 537941 = 538444

Showing the first eight; more decompositions exist.
