Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31584554, here are decompositions:

3 + 31584551 = 31584554
7 + 31584547 = 31584554
13 + 31584541 = 31584554
31 + 31584523 = 31584554
73 + 31584481 = 31584554
97 + 31584457 = 31584554
181 + 31584373 = 31584554
193 + 31584361 = 31584554

Showing the first eight; more decompositions exist.
