Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533124, here are decompositions:

5 + 31533119 = 31533124
23 + 31533101 = 31533124
251 + 31532873 = 31533124
257 + 31532867 = 31533124
347 + 31532777 = 31533124
431 + 31532693 = 31533124
617 + 31532507 = 31533124
647 + 31532477 = 31533124

Showing the first eight; more decompositions exist.
