Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531958, here are decompositions:

47 + 531911 = 531958
101 + 531857 = 531958
131 + 531827 = 531958
137 + 531821 = 531958
227 + 531731 = 531958
257 + 531701 = 531958
269 + 531689 = 531958
347 + 531611 = 531958

Showing the first eight; more decompositions exist.
