Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533248, here are decompositions:

151 + 31533097 = 31533248
157 + 31533091 = 31533248
277 + 31532971 = 31533248
349 + 31532899 = 31533248
367 + 31532881 = 31533248
499 + 31532749 = 31533248
661 + 31532587 = 31533248
709 + 31532539 = 31533248

Showing the first eight; more decompositions exist.
