Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 510930, here are decompositions:

11 + 510919 = 510930
23 + 510907 = 510930
41 + 510889 = 510930
83 + 510847 = 510930
103 + 510827 = 510930
107 + 510823 = 510930
113 + 510817 = 510930
127 + 510803 = 510930

Showing the first eight; more decompositions exist.
