Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31575354, here are decompositions:

17 + 31575337 = 31575354
43 + 31575311 = 31575354
53 + 31575301 = 31575354
73 + 31575281 = 31575354
113 + 31575241 = 31575354
137 + 31575217 = 31575354
191 + 31575163 = 31575354
193 + 31575161 = 31575354

Showing the first eight; more decompositions exist.
