Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517642, here are decompositions:

3 + 517639 = 517642
5 + 517637 = 517642
23 + 517619 = 517642
29 + 517613 = 517642
53 + 517589 = 517642
71 + 517571 = 517642
89 + 517553 = 517642
131 + 517511 = 517642

Showing the first eight; more decompositions exist.
