Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626724, here are decompositions:

167 + 31626557 = 31626724
191 + 31626533 = 31626724
263 + 31626461 = 31626724
317 + 31626407 = 31626724
347 + 31626377 = 31626724
401 + 31626323 = 31626724
491 + 31626233 = 31626724
557 + 31626167 = 31626724

Showing the first eight; more decompositions exist.
