Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489066, here are decompositions:

3 + 31489063 = 31489066
23 + 31489043 = 31489066
29 + 31489037 = 31489066
107 + 31488959 = 31489066
149 + 31488917 = 31489066
239 + 31488827 = 31489066
269 + 31488797 = 31489066
419 + 31488647 = 31489066

Showing the first eight; more decompositions exist.
