Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523822, here are decompositions:

29 + 523793 = 523822
59 + 523763 = 523822
149 + 523673 = 523822
191 + 523631 = 523822
251 + 523571 = 523822
269 + 523553 = 523822
281 + 523541 = 523822
311 + 523511 = 523822

Showing the first eight; more decompositions exist.
