Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534108, here are decompositions:

5 + 31534103 = 31534108
29 + 31534079 = 31534108
41 + 31534067 = 31534108
149 + 31533959 = 31534108
197 + 31533911 = 31534108
269 + 31533839 = 31534108
317 + 31533791 = 31534108
401 + 31533707 = 31534108

Showing the first eight; more decompositions exist.
