Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547492, here are decompositions:

3 + 31547489 = 31547492
13 + 31547479 = 31547492
43 + 31547449 = 31547492
79 + 31547413 = 31547492
211 + 31547281 = 31547492
283 + 31547209 = 31547492
331 + 31547161 = 31547492
349 + 31547143 = 31547492

Showing the first eight; more decompositions exist.
