Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30536, here are decompositions:

7 + 30529 = 30536
19 + 30517 = 30536
43 + 30493 = 30536
67 + 30469 = 30536
109 + 30427 = 30536
223 + 30313 = 30536
229 + 30307 = 30536
277 + 30259 = 30536

Showing the first eight; more decompositions exist.
