Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531706, here are decompositions:

5 + 531701 = 531706
17 + 531689 = 531706
83 + 531623 = 531706
137 + 531569 = 531706
347 + 531359 = 531706
353 + 531353 = 531706
359 + 531347 = 531706
419 + 531287 = 531706

Showing the first eight; more decompositions exist.
