Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513982, here are decompositions:

5 + 513977 = 513982
59 + 513923 = 513982
83 + 513899 = 513982
101 + 513881 = 513982
233 + 513749 = 513982
251 + 513731 = 513982
263 + 513719 = 513982
389 + 513593 = 513982

Showing the first eight; more decompositions exist.
