Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472214, here are decompositions:

5 + 31472209 = 31472214
13 + 31472201 = 31472214
23 + 31472191 = 31472214
31 + 31472183 = 31472214
47 + 31472167 = 31472214
61 + 31472153 = 31472214
71 + 31472143 = 31472214
83 + 31472131 = 31472214

Showing the first eight; more decompositions exist.
