Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494694, here are decompositions:

3 + 31494691 = 31494694
5 + 31494689 = 31494694
83 + 31494611 = 31494694
113 + 31494581 = 31494694
191 + 31494503 = 31494694
197 + 31494497 = 31494694
227 + 31494467 = 31494694
251 + 31494443 = 31494694

Showing the first eight; more decompositions exist.
