Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498308, here are decompositions:

19 + 31498289 = 31498308
29 + 31498279 = 31498308
31 + 31498277 = 31498308
109 + 31498199 = 31498308
157 + 31498151 = 31498308
197 + 31498111 = 31498308
239 + 31498069 = 31498308
269 + 31498039 = 31498308

Showing the first eight; more decompositions exist.
