Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531922, here are decompositions:

3 + 531919 = 531922
11 + 531911 = 531922
59 + 531863 = 531922
89 + 531833 = 531922
101 + 531821 = 531922
191 + 531731 = 531922
233 + 531689 = 531922
311 + 531611 = 531922

Showing the first eight; more decompositions exist.
