Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470024, here are decompositions:

11 + 31470013 = 31470024
37 + 31469987 = 31470024
71 + 31469953 = 31470024
101 + 31469923 = 31470024
163 + 31469861 = 31470024
167 + 31469857 = 31470024
211 + 31469813 = 31470024
227 + 31469797 = 31470024

Showing the first eight; more decompositions exist.
