Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584534, here are decompositions:

11 + 31584523 = 31584534
53 + 31584481 = 31584534
103 + 31584431 = 31584534
127 + 31584407 = 31584534
151 + 31584383 = 31584534
173 + 31584361 = 31584534
197 + 31584337 = 31584534
211 + 31584323 = 31584534

Showing the first eight; more decompositions exist.
