Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494454, here are decompositions:

11 + 31494443 = 31494454
23 + 31494431 = 31494454
53 + 31494401 = 31494454
107 + 31494347 = 31494454
191 + 31494263 = 31494454
197 + 31494257 = 31494454
293 + 31494161 = 31494454
311 + 31494143 = 31494454

Showing the first eight; more decompositions exist.
