Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521894, here are decompositions:

7 + 521887 = 521894
13 + 521881 = 521894
103 + 521791 = 521894
127 + 521767 = 521894
151 + 521743 = 521894
223 + 521671 = 521894
313 + 521581 = 521894
337 + 521557 = 521894

Showing the first eight; more decompositions exist.
