Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489222, here are decompositions:

5 + 31489217 = 31489222
29 + 31489193 = 31489222
41 + 31489181 = 31489222
53 + 31489169 = 31489222
131 + 31489091 = 31489222
179 + 31489043 = 31489222
251 + 31488971 = 31489222
263 + 31488959 = 31489222

Showing the first eight; more decompositions exist.
