Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 523730, here are decompositions:

13 + 523717 = 523730
61 + 523669 = 523730
73 + 523657 = 523730
127 + 523603 = 523730
157 + 523573 = 523730
211 + 523519 = 523730
241 + 523489 = 523730
271 + 523459 = 523730

Showing the first eight; more decompositions exist.
