Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584412, here are decompositions:

5 + 31584407 = 31584412
11 + 31584401 = 31584412
23 + 31584389 = 31584412
29 + 31584383 = 31584412
89 + 31584323 = 31584412
113 + 31584299 = 31584412
131 + 31584281 = 31584412
149 + 31584263 = 31584412

Showing the first eight; more decompositions exist.
