Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489060, here are decompositions:

17 + 31489043 = 31489060
23 + 31489037 = 31489060
89 + 31488971 = 31489060
101 + 31488959 = 31489060
149 + 31488911 = 31489060
233 + 31488827 = 31489060
263 + 31488797 = 31489060
293 + 31488767 = 31489060

Showing the first eight; more decompositions exist.
