Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494406, here are decompositions:

5 + 31494401 = 31494406
17 + 31494389 = 31494406
59 + 31494347 = 31494406
113 + 31494293 = 31494406
149 + 31494257 = 31494406
227 + 31494179 = 31494406
263 + 31494143 = 31494406
353 + 31494053 = 31494406

Showing the first eight; more decompositions exist.
