Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584342, here are decompositions:

5 + 31584337 = 31584342
19 + 31584323 = 31584342
43 + 31584299 = 31584342
61 + 31584281 = 31584342
79 + 31584263 = 31584342
109 + 31584233 = 31584342
131 + 31584211 = 31584342
149 + 31584193 = 31584342

Showing the first eight; more decompositions exist.
