Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494888, here are decompositions:

71 + 31494817 = 31494888
79 + 31494809 = 31494888
107 + 31494781 = 31494888
151 + 31494737 = 31494888
167 + 31494721 = 31494888
181 + 31494707 = 31494888
197 + 31494691 = 31494888
199 + 31494689 = 31494888

Showing the first eight; more decompositions exist.
