Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531798, here are decompositions:

5 + 531793 = 531798
67 + 531731 = 531798
97 + 531701 = 531798
109 + 531689 = 531798
131 + 531667 = 531798
167 + 531631 = 531798
227 + 531571 = 531798
229 + 531569 = 531798

Showing the first eight; more decompositions exist.
