Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517860, here are decompositions:

29 + 517831 = 517860
37 + 517823 = 517860
43 + 517817 = 517860
113 + 517747 = 517860
127 + 517733 = 517860
131 + 517729 = 517860
139 + 517721 = 517860
149 + 517711 = 517860

Showing the first eight; more decompositions exist.
