Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517830, here are decompositions:

7 + 517823 = 517830
13 + 517817 = 517830
83 + 517747 = 517830
97 + 517733 = 517830
101 + 517729 = 517830
109 + 517721 = 517830
113 + 517717 = 517830
191 + 517639 = 517830

Showing the first eight; more decompositions exist.
