Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489048, here are decompositions:

5 + 31489043 = 31489048
11 + 31489037 = 31489048
89 + 31488959 = 31489048
131 + 31488917 = 31489048
137 + 31488911 = 31489048
251 + 31488797 = 31489048
281 + 31488767 = 31489048
401 + 31488647 = 31489048

Showing the first eight; more decompositions exist.
