Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584404, here are decompositions:

3 + 31584401 = 31584404
31 + 31584373 = 31584404
43 + 31584361 = 31584404
67 + 31584337 = 31584404
97 + 31584307 = 31584404
157 + 31584247 = 31584404
193 + 31584211 = 31584404
211 + 31584193 = 31584404

Showing the first eight; more decompositions exist.
