Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517890, here are decompositions:

13 + 517877 = 517890
17 + 517873 = 517890
29 + 517861 = 517890
59 + 517831 = 517890
67 + 517823 = 517890
73 + 517817 = 517890
151 + 517739 = 517890
157 + 517733 = 517890

Showing the first eight; more decompositions exist.
