Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30506, here are decompositions:

13 + 30493 = 30506
37 + 30469 = 30506
79 + 30427 = 30506
103 + 30403 = 30506
139 + 30367 = 30506
193 + 30313 = 30506
199 + 30307 = 30506
283 + 30223 = 30506

Showing the first eight; more decompositions exist.
