Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505332, here are decompositions:

3 + 31505329 = 31505332
11 + 31505321 = 31505332
29 + 31505303 = 31505332
149 + 31505183 = 31505332
191 + 31505141 = 31505332
233 + 31505099 = 31505332
251 + 31505081 = 31505332
293 + 31505039 = 31505332

Showing the first eight; more decompositions exist.
