Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489264, here are decompositions:

5 + 31489259 = 31489264
17 + 31489247 = 31489264
47 + 31489217 = 31489264
71 + 31489193 = 31489264
83 + 31489181 = 31489264
167 + 31489097 = 31489264
173 + 31489091 = 31489264
227 + 31489037 = 31489264

Showing the first eight; more decompositions exist.
