Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498206, here are decompositions:

7 + 31498199 = 31498206
13 + 31498193 = 31498206
17 + 31498189 = 31498206
83 + 31498123 = 31498206
137 + 31498069 = 31498206
163 + 31498043 = 31498206
167 + 31498039 = 31498206
197 + 31498009 = 31498206

Showing the first eight; more decompositions exist.
