Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584410, here are decompositions:

3 + 31584407 = 31584410
37 + 31584373 = 31584410
73 + 31584337 = 31584410
103 + 31584307 = 31584410
163 + 31584247 = 31584410
199 + 31584211 = 31584410
271 + 31584139 = 31584410
367 + 31584043 = 31584410

Showing the first eight; more decompositions exist.
