Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31528474, here are decompositions:

23 + 31528451 = 31528474
41 + 31528433 = 31528474
101 + 31528373 = 31528474
137 + 31528337 = 31528474
191 + 31528283 = 31528474
233 + 31528241 = 31528474
317 + 31528157 = 31528474
347 + 31528127 = 31528474

Showing the first eight; more decompositions exist.
