Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31550432, here are decompositions:

31 + 31550401 = 31550432
61 + 31550371 = 31550432
79 + 31550353 = 31550432
103 + 31550329 = 31550432
181 + 31550251 = 31550432
211 + 31550221 = 31550432
283 + 31550149 = 31550432
313 + 31550119 = 31550432

Showing the first eight; more decompositions exist.
