Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31547458, here are decompositions:

17 + 31547441 = 31547458
101 + 31547357 = 31547458
191 + 31547267 = 31547458
197 + 31547261 = 31547458
227 + 31547231 = 31547458
281 + 31547177 = 31547458
311 + 31547147 = 31547458
419 + 31547039 = 31547458

Showing the first eight; more decompositions exist.
