Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510920, here are decompositions:

13 + 510907 = 510920
31 + 510889 = 510920
73 + 510847 = 510920
97 + 510823 = 510920
103 + 510817 = 510920
127 + 510793 = 510920
211 + 510709 = 510920
229 + 510691 = 510920

Showing the first eight; more decompositions exist.
