Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520844, here are decompositions:

3 + 520841 = 520844
7 + 520837 = 520844
31 + 520813 = 520844
97 + 520747 = 520844
127 + 520717 = 520844
211 + 520633 = 520844
223 + 520621 = 520844
277 + 520567 = 520844

Showing the first eight; more decompositions exist.
