Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584374, here are decompositions:

13 + 31584361 = 31584374
37 + 31584337 = 31584374
67 + 31584307 = 31584374
127 + 31584247 = 31584374
163 + 31584211 = 31584374
181 + 31584193 = 31584374
307 + 31584067 = 31584374
331 + 31584043 = 31584374

Showing the first eight; more decompositions exist.
