Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 30850, here are decompositions:

11 + 30839 = 30850
41 + 30809 = 30850
47 + 30803 = 30850
137 + 30713 = 30850
173 + 30677 = 30850
179 + 30671 = 30850
257 + 30593 = 30850
293 + 30557 = 30850

Showing the first eight; more decompositions exist.
