Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31498476, here are decompositions:

5 + 31498471 = 31498476
7 + 31498469 = 31498476
13 + 31498463 = 31498476
109 + 31498367 = 31498476
127 + 31498349 = 31498476
197 + 31498279 = 31498476
199 + 31498277 = 31498476
223 + 31498253 = 31498476

Showing the first eight; more decompositions exist.
