Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30408, here are decompositions:

5 + 30403 = 30408
17 + 30391 = 30408
19 + 30389 = 30408
41 + 30367 = 30408
61 + 30347 = 30408
67 + 30341 = 30408
89 + 30319 = 30408
101 + 30307 = 30408

Showing the first eight; more decompositions exist.
