Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529830, here are decompositions:

11 + 529819 = 529830
17 + 529813 = 529830
19 + 529811 = 529830
23 + 529807 = 529830
79 + 529751 = 529830
83 + 529747 = 529830
89 + 529741 = 529830
107 + 529723 = 529830

Showing the first eight; more decompositions exist.
