Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489224, here are decompositions:

7 + 31489217 = 31489224
31 + 31489193 = 31489224
43 + 31489181 = 31489224
47 + 31489177 = 31489224
127 + 31489097 = 31489224
181 + 31489043 = 31489224
197 + 31489027 = 31489224
233 + 31488991 = 31489224

Showing the first eight; more decompositions exist.
