Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534306, here are decompositions:

5 + 31534301 = 31534306
59 + 31534247 = 31534306
107 + 31534199 = 31534306
137 + 31534169 = 31534306
227 + 31534079 = 31534306
233 + 31534073 = 31534306
239 + 31534067 = 31534306
347 + 31533959 = 31534306

Showing the first eight; more decompositions exist.
