Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505334, here are decompositions:

5 + 31505329 = 31505334
13 + 31505321 = 31505334
31 + 31505303 = 31505334
37 + 31505297 = 31505334
41 + 31505293 = 31505334
151 + 31505183 = 31505334
191 + 31505143 = 31505334
193 + 31505141 = 31505334

Showing the first eight; more decompositions exist.
