Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 500920, here are decompositions:

11 + 500909 = 500920
29 + 500891 = 500920
47 + 500873 = 500920
59 + 500861 = 500920
89 + 500831 = 500920
113 + 500807 = 500920
179 + 500741 = 500920
191 + 500729 = 500920

Showing the first eight; more decompositions exist.
