Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494496, here are decompositions:

17 + 31494479 = 31494496
29 + 31494467 = 31494496
53 + 31494443 = 31494496
107 + 31494389 = 31494496
149 + 31494347 = 31494496
233 + 31494263 = 31494496
239 + 31494257 = 31494496
317 + 31494179 = 31494496

Showing the first eight; more decompositions exist.
