Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513930, here are decompositions:

7 + 513923 = 513930
13 + 513917 = 513930
31 + 513899 = 513930
59 + 513871 = 513930
89 + 513841 = 513930
101 + 513829 = 513930
149 + 513781 = 513930
163 + 513767 = 513930

Showing the first eight; more decompositions exist.
