Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521874, here are decompositions:

5 + 521869 = 521874
13 + 521861 = 521874
43 + 521831 = 521874
61 + 521813 = 521874
83 + 521791 = 521874
97 + 521777 = 521874
107 + 521767 = 521874
131 + 521743 = 521874

Showing the first eight; more decompositions exist.
