Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 529730, here are decompositions:

7 + 529723 = 529730
37 + 529693 = 529730
43 + 529687 = 529730
73 + 529657 = 529730
127 + 529603 = 529730
151 + 529579 = 529730
199 + 529531 = 529730
211 + 529519 = 529730

Showing the first eight; more decompositions exist.
