Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31603050, here are decompositions:

23 + 31603027 = 31603050
41 + 31603009 = 31603050
151 + 31602899 = 31603050
173 + 31602877 = 31603050
191 + 31602859 = 31603050
197 + 31602853 = 31603050
257 + 31602793 = 31603050
359 + 31602691 = 31603050

Showing the first eight; more decompositions exist.
