Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531682, here are decompositions:

59 + 531623 = 531682
71 + 531611 = 531682
101 + 531581 = 531682
113 + 531569 = 531682
131 + 531551 = 531682
383 + 531299 = 531682
401 + 531281 = 531682
419 + 531263 = 531682

Showing the first eight; more decompositions exist.
