Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521884, here are decompositions:

3 + 521881 = 521884
5 + 521879 = 521884
23 + 521861 = 521884
53 + 521831 = 521884
71 + 521813 = 521884
107 + 521777 = 521884
131 + 521753 = 521884
191 + 521693 = 521884

Showing the first eight; more decompositions exist.
