Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30530, here are decompositions:

13 + 30517 = 30530
37 + 30493 = 30530
61 + 30469 = 30530
103 + 30427 = 30530
127 + 30403 = 30530
139 + 30391 = 30530
163 + 30367 = 30530
211 + 30319 = 30530

Showing the first eight; more decompositions exist.
