Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472454, here are decompositions:

5 + 31472449 = 31472454
17 + 31472437 = 31472454
103 + 31472351 = 31472454
163 + 31472291 = 31472454
193 + 31472261 = 31472454
263 + 31472191 = 31472454
271 + 31472183 = 31472454
311 + 31472143 = 31472454

Showing the first eight; more decompositions exist.
