Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513900, here are decompositions:

19 + 513881 = 513900
29 + 513871 = 513900
59 + 513841 = 513900
61 + 513839 = 513900
71 + 513829 = 513900
131 + 513769 = 513900
139 + 513761 = 513900
151 + 513749 = 513900

Showing the first eight; more decompositions exist.
