Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513888, here are decompositions:

7 + 513881 = 513888
17 + 513871 = 513888
47 + 513841 = 513888
59 + 513829 = 513888
107 + 513781 = 513888
127 + 513761 = 513888
139 + 513749 = 513888
149 + 513739 = 513888

Showing the first eight; more decompositions exist.
