Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31463352, here are decompositions:

23 + 31463329 = 31463352
31 + 31463321 = 31463352
71 + 31463281 = 31463352
83 + 31463269 = 31463352
103 + 31463249 = 31463352
139 + 31463213 = 31463352
149 + 31463203 = 31463352
191 + 31463161 = 31463352

Showing the first eight; more decompositions exist.
