Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489054, here are decompositions:

11 + 31489043 = 31489054
17 + 31489037 = 31489054
83 + 31488971 = 31489054
137 + 31488917 = 31489054
227 + 31488827 = 31489054
257 + 31488797 = 31489054
491 + 31488563 = 31489054
557 + 31488497 = 31489054

Showing the first eight; more decompositions exist.
