Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31505362, here are decompositions:

3 + 31505359 = 31505362
29 + 31505333 = 31505362
41 + 31505321 = 31505362
59 + 31505303 = 31505362
149 + 31505213 = 31505362
173 + 31505189 = 31505362
179 + 31505183 = 31505362
263 + 31505099 = 31505362

Showing the first eight; more decompositions exist.
