Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584522, here are decompositions:

23 + 31584499 = 31584522
41 + 31584481 = 31584522
83 + 31584439 = 31584522
139 + 31584383 = 31584522
149 + 31584373 = 31584522
199 + 31584323 = 31584522
223 + 31584299 = 31584522
241 + 31584281 = 31584522

Showing the first eight; more decompositions exist.
