Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494616, here are decompositions:

5 + 31494611 = 31494616
107 + 31494509 = 31494616
113 + 31494503 = 31494616
137 + 31494479 = 31494616
149 + 31494467 = 31494616
173 + 31494443 = 31494616
227 + 31494389 = 31494616
269 + 31494347 = 31494616

Showing the first eight; more decompositions exist.
