Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472436, here are decompositions:

97 + 31472339 = 31472436
197 + 31472239 = 31472436
227 + 31472209 = 31472436
257 + 31472179 = 31472436
269 + 31472167 = 31472436
277 + 31472159 = 31472436
283 + 31472153 = 31472436
293 + 31472143 = 31472436

Showing the first eight; more decompositions exist.
