Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489204, here are decompositions:

11 + 31489193 = 31489204
23 + 31489181 = 31489204
107 + 31489097 = 31489204
113 + 31489091 = 31489204
167 + 31489037 = 31489204
233 + 31488971 = 31489204
293 + 31488911 = 31489204
557 + 31488647 = 31489204

Showing the first eight; more decompositions exist.
