Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472294, here are decompositions:

3 + 31472291 = 31472294
103 + 31472191 = 31472294
127 + 31472167 = 31472294
151 + 31472143 = 31472294
163 + 31472131 = 31472294
241 + 31472053 = 31472294
283 + 31472011 = 31472294
463 + 31471831 = 31472294

Showing the first eight; more decompositions exist.
