Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584426, here are decompositions:

19 + 31584407 = 31584426
37 + 31584389 = 31584426
43 + 31584383 = 31584426
53 + 31584373 = 31584426
89 + 31584337 = 31584426
103 + 31584323 = 31584426
127 + 31584299 = 31584426
163 + 31584263 = 31584426

Showing the first eight; more decompositions exist.
