Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472466, here are decompositions:

17 + 31472449 = 31472466
29 + 31472437 = 31472466
107 + 31472359 = 31472466
127 + 31472339 = 31472466
173 + 31472293 = 31472466
227 + 31472239 = 31472466
257 + 31472209 = 31472466
283 + 31472183 = 31472466

Showing the first eight; more decompositions exist.
