Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31506934, here are decompositions:

3 + 31506931 = 31506934
5 + 31506929 = 31506934
23 + 31506911 = 31506934
47 + 31506887 = 31506934
113 + 31506821 = 31506934
191 + 31506743 = 31506934
257 + 31506677 = 31506934
293 + 31506641 = 31506934

Showing the first eight; more decompositions exist.
