Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534336, here are decompositions:

3 + 31534333 = 31534336
89 + 31534247 = 31534336
137 + 31534199 = 31534336
149 + 31534187 = 31534336
167 + 31534169 = 31534336
233 + 31534103 = 31534336
257 + 31534079 = 31534336
263 + 31534073 = 31534336

Showing the first eight; more decompositions exist.
