Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31475324, here are decompositions:

3 + 31475321 = 31475324
7 + 31475317 = 31475324
37 + 31475287 = 31475324
73 + 31475251 = 31475324
193 + 31475131 = 31475324
241 + 31475083 = 31475324
271 + 31475053 = 31475324
457 + 31474867 = 31475324

Showing the first eight; more decompositions exist.
