Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31499184, here are decompositions:

23 + 31499161 = 31499184
47 + 31499137 = 31499184
107 + 31499077 = 31499184
127 + 31499057 = 31499184
151 + 31499033 = 31499184
163 + 31499021 = 31499184
181 + 31499003 = 31499184
191 + 31498993 = 31499184

Showing the first eight; more decompositions exist.
