Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 517906, here are decompositions:

5 + 517901 = 517906
29 + 517877 = 517906
83 + 517823 = 517906
89 + 517817 = 517906
167 + 517739 = 517906
173 + 517733 = 517906
269 + 517637 = 517906
293 + 517613 = 517906

Showing the first eight; more decompositions exist.
