Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531906, here are decompositions:

5 + 531901 = 531906
29 + 531877 = 531906
43 + 531863 = 531906
59 + 531847 = 531906
73 + 531833 = 531906
79 + 531827 = 531906
83 + 531823 = 531906
107 + 531799 = 531906

Showing the first eight; more decompositions exist.
