Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 518020, here are decompositions:

3 + 518017 = 518020
29 + 517991 = 518020
53 + 517967 = 518020
71 + 517949 = 518020
89 + 517931 = 518020
101 + 517919 = 518020
197 + 517823 = 518020
281 + 517739 = 518020

Showing the first eight; more decompositions exist.
