Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517742, here are decompositions:

3 + 517739 = 517742
13 + 517729 = 517742
31 + 517711 = 517742
103 + 517639 = 517742
139 + 517603 = 517742
193 + 517549 = 517742
229 + 517513 = 517742
241 + 517501 = 517742

Showing the first eight; more decompositions exist.
