Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521814, here are decompositions:

5 + 521809 = 521814
23 + 521791 = 521814
37 + 521777 = 521814
47 + 521767 = 521814
61 + 521753 = 521814
71 + 521743 = 521814
107 + 521707 = 521814
157 + 521657 = 521814

Showing the first eight; more decompositions exist.
