Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531826, here are decompositions:

3 + 531823 = 531826
5 + 531821 = 531826
137 + 531689 = 531826
257 + 531569 = 531826
443 + 531383 = 531826
467 + 531359 = 531826
479 + 531347 = 531826
563 + 531263 = 531826

Showing the first eight; more decompositions exist.
