Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494354, here are decompositions:

7 + 31494347 = 31494354
53 + 31494301 = 31494354
61 + 31494293 = 31494354
97 + 31494257 = 31494354
107 + 31494247 = 31494354
113 + 31494241 = 31494354
193 + 31494161 = 31494354
197 + 31494157 = 31494354

Showing the first eight; more decompositions exist.
