Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31497494, here are decompositions:

3 + 31497491 = 31497494
31 + 31497463 = 31497494
103 + 31497391 = 31497494
157 + 31497337 = 31497494
181 + 31497313 = 31497494
211 + 31497283 = 31497494
271 + 31497223 = 31497494
307 + 31497187 = 31497494

Showing the first eight; more decompositions exist.
