Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472316, here are decompositions:

23 + 31472293 = 31472316
107 + 31472209 = 31472316
137 + 31472179 = 31472316
149 + 31472167 = 31472316
157 + 31472159 = 31472316
163 + 31472153 = 31472316
167 + 31472149 = 31472316
173 + 31472143 = 31472316

Showing the first eight; more decompositions exist.
