Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623722, here are decompositions:

19 + 31623703 = 31623722
199 + 31623523 = 31623722
211 + 31623511 = 31623722
223 + 31623499 = 31623722
241 + 31623481 = 31623722
283 + 31623439 = 31623722
349 + 31623373 = 31623722
379 + 31623343 = 31623722

Showing the first eight; more decompositions exist.
