Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488244, here are decompositions:

17 + 31488227 = 31488244
41 + 31488203 = 31488244
83 + 31488161 = 31488244
107 + 31488137 = 31488244
173 + 31488071 = 31488244
191 + 31488053 = 31488244
251 + 31487993 = 31488244
461 + 31487783 = 31488244

Showing the first eight; more decompositions exist.
