Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534348, here are decompositions:

5 + 31534343 = 31534348
47 + 31534301 = 31534348
101 + 31534247 = 31534348
107 + 31534241 = 31534348
149 + 31534199 = 31534348
179 + 31534169 = 31534348
227 + 31534121 = 31534348
269 + 31534079 = 31534348

Showing the first eight; more decompositions exist.
