Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30480, here are decompositions:

11 + 30469 = 30480
13 + 30467 = 30480
31 + 30449 = 30480
53 + 30427 = 30480
89 + 30391 = 30480
113 + 30367 = 30480
139 + 30341 = 30480
157 + 30323 = 30480

Showing the first eight; more decompositions exist.
