Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31489096, here are decompositions:

5 + 31489091 = 31489096
17 + 31489079 = 31489096
53 + 31489043 = 31489096
59 + 31489037 = 31489096
137 + 31488959 = 31489096
179 + 31488917 = 31489096
269 + 31488827 = 31489096
449 + 31488647 = 31489096

Showing the first eight; more decompositions exist.
