Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584396, here are decompositions:

7 + 31584389 = 31584396
13 + 31584383 = 31584396
23 + 31584373 = 31584396
59 + 31584337 = 31584396
73 + 31584323 = 31584396
89 + 31584307 = 31584396
97 + 31584299 = 31584396
149 + 31584247 = 31584396

Showing the first eight; more decompositions exist.
