Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531754, here are decompositions:

23 + 531731 = 531754
53 + 531701 = 531754
131 + 531623 = 531754
173 + 531581 = 531754
233 + 531521 = 531754
257 + 531497 = 531754
401 + 531353 = 531754
467 + 531287 = 531754

Showing the first eight; more decompositions exist.
