Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531736, here are decompositions:

5 + 531731 = 531736
47 + 531689 = 531736
113 + 531623 = 531736
167 + 531569 = 531736
239 + 531497 = 531736
353 + 531383 = 531736
383 + 531353 = 531736
389 + 531347 = 531736

Showing the first eight; more decompositions exist.
