Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584408, here are decompositions:

7 + 31584401 = 31584408
19 + 31584389 = 31584408
47 + 31584361 = 31584408
71 + 31584337 = 31584408
101 + 31584307 = 31584408
109 + 31584299 = 31584408
127 + 31584281 = 31584408
197 + 31584211 = 31584408

Showing the first eight; more decompositions exist.
