Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513980, here are decompositions:

3 + 513977 = 513980
37 + 513943 = 513980
43 + 513937 = 513980
109 + 513871 = 513980
139 + 513841 = 513980
151 + 513829 = 513980
199 + 513781 = 513980
211 + 513769 = 513980

Showing the first eight; more decompositions exist.
