Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513978, here are decompositions:

41 + 513937 = 513978
61 + 513917 = 513978
79 + 513899 = 513978
97 + 513881 = 513978
107 + 513871 = 513978
137 + 513841 = 513978
139 + 513839 = 513978
149 + 513829 = 513978

Showing the first eight; more decompositions exist.
