Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 520874, here are decompositions:

7 + 520867 = 520874
37 + 520837 = 520874
61 + 520813 = 520874
127 + 520747 = 520874
157 + 520717 = 520874
241 + 520633 = 520874
307 + 520567 = 520874
463 + 520411 = 520874

Showing the first eight; more decompositions exist.
