Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521832, here are decompositions:

13 + 521819 = 521832
19 + 521813 = 521832
23 + 521809 = 521832
41 + 521791 = 521832
43 + 521789 = 521832
79 + 521753 = 521832
83 + 521749 = 521832
89 + 521743 = 521832

Showing the first eight; more decompositions exist.
