Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31470254, here are decompositions:

31 + 31470223 = 31470254
37 + 31470217 = 31470254
61 + 31470193 = 31470254
103 + 31470151 = 31470254
157 + 31470097 = 31470254
181 + 31470073 = 31470254
241 + 31470013 = 31470254
331 + 31469923 = 31470254

Showing the first eight; more decompositions exist.
