Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 531946, here are decompositions:

83 + 531863 = 531946
89 + 531857 = 531946
113 + 531833 = 531946
257 + 531689 = 531946
449 + 531497 = 531946
563 + 531383 = 531946
587 + 531359 = 531946
593 + 531353 = 531946

Showing the first eight; more decompositions exist.
