Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31628248, here are decompositions:

149 + 31628099 = 31628248
227 + 31628021 = 31628248
269 + 31627979 = 31628248
317 + 31627931 = 31628248
359 + 31627889 = 31628248
521 + 31627727 = 31628248
599 + 31627649 = 31628248
647 + 31627601 = 31628248

Showing the first eight; more decompositions exist.
