Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498008, here are decompositions:

5 + 31498003 = 31498008
11 + 31497997 = 31498008
29 + 31497979 = 31498008
67 + 31497941 = 31498008
79 + 31497929 = 31498008
137 + 31497871 = 31498008
149 + 31497859 = 31498008
181 + 31497827 = 31498008

Showing the first eight; more decompositions exist.
