Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 521910, here are decompositions:

7 + 521903 = 521910
13 + 521897 = 521910
23 + 521887 = 521910
29 + 521881 = 521910
31 + 521879 = 521910
41 + 521869 = 521910
79 + 521831 = 521910
97 + 521813 = 521910

Showing the first eight; more decompositions exist.
