Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31488334, here are decompositions:

5 + 31488329 = 31488334
11 + 31488323 = 31488334
41 + 31488293 = 31488334
107 + 31488227 = 31488334
131 + 31488203 = 31488334
173 + 31488161 = 31488334
197 + 31488137 = 31488334
233 + 31488101 = 31488334

Showing the first eight; more decompositions exist.
