Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523408, here are decompositions:

5 + 523403 = 523408
59 + 523349 = 523408
101 + 523307 = 523408
239 + 523169 = 523408
311 + 523097 = 523408
359 + 523049 = 523408
401 + 523007 = 523408
419 + 522989 = 523408

Showing the first eight; more decompositions exist.
