Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31494408, here are decompositions:

7 + 31494401 = 31494408
19 + 31494389 = 31494408
61 + 31494347 = 31494408
107 + 31494301 = 31494408
151 + 31494257 = 31494408
167 + 31494241 = 31494408
229 + 31494179 = 31494408
251 + 31494157 = 31494408

Showing the first eight; more decompositions exist.
