Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30808, here are decompositions:

5 + 30803 = 30808
101 + 30707 = 30808
131 + 30677 = 30808
137 + 30671 = 30808
251 + 30557 = 30808
269 + 30539 = 30808
311 + 30497 = 30808
317 + 30491 = 30808

Showing the first eight; more decompositions exist.
