Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533244, here are decompositions:

53 + 31533191 = 31533244
101 + 31533143 = 31533244
263 + 31532981 = 31533244
467 + 31532777 = 31533244
557 + 31532687 = 31533244
647 + 31532597 = 31533244
983 + 31532261 = 31533244
1103 + 31532141 = 31533244

Showing the first eight; more decompositions exist.
