Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31472448, here are decompositions:

11 + 31472437 = 31472448
89 + 31472359 = 31472448
97 + 31472351 = 31472448
109 + 31472339 = 31472448
157 + 31472291 = 31472448
239 + 31472209 = 31472448
257 + 31472191 = 31472448
269 + 31472179 = 31472448

Showing the first eight; more decompositions exist.
