Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472556, here are decompositions:

19 + 31472537 = 31472556
67 + 31472489 = 31472556
107 + 31472449 = 31472556
197 + 31472359 = 31472556
263 + 31472293 = 31472556
317 + 31472239 = 31472556
347 + 31472209 = 31472556
373 + 31472183 = 31472556

Showing the first eight; more decompositions exist.
