Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513018, here are decompositions:

5 + 513013 = 513018
17 + 513001 = 513018
19 + 512999 = 513018
29 + 512989 = 513018
41 + 512977 = 513018
59 + 512959 = 513018
89 + 512929 = 513018
97 + 512921 = 513018

Showing the first eight; more decompositions exist.
