Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30550, here are decompositions:

11 + 30539 = 30550
41 + 30509 = 30550
53 + 30497 = 30550
59 + 30491 = 30550
83 + 30467 = 30550
101 + 30449 = 30550
227 + 30323 = 30550
257 + 30293 = 30550

Showing the first eight; more decompositions exist.
