Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505482, here are decompositions:

23 + 31505459 = 31505482
101 + 31505381 = 31505482
149 + 31505333 = 31505482
179 + 31505303 = 31505482
269 + 31505213 = 31505482
293 + 31505189 = 31505482
383 + 31505099 = 31505482
401 + 31505081 = 31505482

Showing the first eight; more decompositions exist.
