Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472334, here are decompositions:

41 + 31472293 = 31472334
43 + 31472291 = 31472334
73 + 31472261 = 31472334
151 + 31472183 = 31472334
167 + 31472167 = 31472334
181 + 31472153 = 31472334
191 + 31472143 = 31472334
211 + 31472123 = 31472334

Showing the first eight; more decompositions exist.
