Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623548, here are decompositions:

37 + 31623511 = 31623548
67 + 31623481 = 31623548
109 + 31623439 = 31623548
127 + 31623421 = 31623548
211 + 31623337 = 31623548
337 + 31623211 = 31623548
349 + 31623199 = 31623548
367 + 31623181 = 31623548

Showing the first eight; more decompositions exist.
