Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523858, here are decompositions:

11 + 523847 = 523858
29 + 523829 = 523858
191 + 523667 = 523858
227 + 523631 = 523858
281 + 523577 = 523858
317 + 523541 = 523858
347 + 523511 = 523858
431 + 523427 = 523858

Showing the first eight; more decompositions exist.
