Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472472, here are decompositions:

23 + 31472449 = 31472472
113 + 31472359 = 31472472
179 + 31472293 = 31472472
181 + 31472291 = 31472472
211 + 31472261 = 31472472
233 + 31472239 = 31472472
263 + 31472209 = 31472472
271 + 31472201 = 31472472

Showing the first eight; more decompositions exist.
