Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 513768, here are decompositions:

7 + 513761 = 513768
19 + 513749 = 513768
29 + 513739 = 513768
37 + 513731 = 513768
41 + 513727 = 513768
71 + 513697 = 513768
89 + 513679 = 513768
127 + 513641 = 513768

Showing the first eight; more decompositions exist.
