Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531694, here are decompositions:

5 + 531689 = 531694
71 + 531623 = 531694
83 + 531611 = 531694
113 + 531581 = 531694
173 + 531521 = 531694
197 + 531497 = 531694
311 + 531383 = 531694
347 + 531347 = 531694

Showing the first eight; more decompositions exist.
