Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498266, here are decompositions:

13 + 31498253 = 31498266
53 + 31498213 = 31498266
67 + 31498199 = 31498266
73 + 31498193 = 31498266
179 + 31498087 = 31498266
197 + 31498069 = 31498266
223 + 31498043 = 31498266
227 + 31498039 = 31498266

Showing the first eight; more decompositions exist.
