Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505350, here are decompositions:

17 + 31505333 = 31505350
29 + 31505321 = 31505350
47 + 31505303 = 31505350
53 + 31505297 = 31505350
137 + 31505213 = 31505350
167 + 31505183 = 31505350
251 + 31505099 = 31505350
269 + 31505081 = 31505350

Showing the first eight; more decompositions exist.
