Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472484, here are decompositions:

5 + 31472479 = 31472484
47 + 31472437 = 31472484
191 + 31472293 = 31472484
193 + 31472291 = 31472484
223 + 31472261 = 31472484
283 + 31472201 = 31472484
293 + 31472191 = 31472484
317 + 31472167 = 31472484

Showing the first eight; more decompositions exist.
